Which location will yield the most HKs?

Well I think most of the people who are gonna be hardcore farming honor, will have had their epic mounts for a while now. Tho rank 3 is definitely something that a lot of people would like.

Your list is solid, but i would add:

Mass battles in Hillsbrad Foothills

Most likely the best candidate.

Why Hillsbrad specifically? It's been quite empty the last few times I was there, I only use the TM flight path to visit Scholo.

I think there are a couple reasons for this.

1) The nostalgia factor. Hillsbrad was a huge hub for world pvp back in the day.

2) Baiting. Since it's a questing zone it might be an easy way to pick on some lower level people and hopefully have them either log on their mains or call for other 60s to come help.

There are probably more reasons, but these are the best I can think of.

Just remind that getting dishonorable kills (which means that someone in your party kills a grey player OR FACTION NPC) will give a quite significative honor contribution loss. This, I think, makes city raid not optimal farm honor. Honestly I would make a group of 5 and wander felwood/winter spring. There you will find more solo farming players to stomp. Not a honourable things to do, but incidentally good way to gain honor.

I think killing players never results in DHKs, but you're right I think raiding cities is possibly a bad idea for Honor farming... which is kind of strange actually. It's much more honorable to raid Stormwind than it is to prey on leveling players. I think we'll probably end up fighting people at BR because that's where the high level players go.

Nobody will step into cities because of DHKs. Maybe some bored rogues but enemies can unflag so it's not worth.

Ganking raids while in a raid will likely yield shit honor. Meta will probably be 3-5 man gank squads.

so they can reach Rank 3 and buy an epic mount with a 10% discount.

When I dinged lvl 60 I had friendly or honored (whichever provides the 10% discount) with my own faction for a long time by then, so am I missing something here or I did something exceptionally right?

I think killing players never results in DHKs,

I was so sure that low level players would give you DHK, but cannot find any evidence.. means I must be wrong!
To be honest, it would make more sense the other way around :P

What I would do is setup a squad with 100% mounts and travel most farmed places in Felwood / Winterspring, without stopping in a place in particular. Satyrs, Plague Horrors and Furbolgs in Felwood, fly to winterspring, kill people outside town, check all furbolg towns while going back to felwood, or something like that.

* Major cities (with a raid)
* Blackrock Mountain (intercept dungeon groups)
* Gurubashi Arena
* Questing zones (easy kills on level 50+ players)
* Farming spots

Major cities wont be a thing because many people are unflagged and DK's.
BRM will be a good spot because its high traffic BUT, there are better spots that have less 60's. The goal is honor per hour, not fair fights where you can be outnumbered.
Gurubashi is ehhh...
Questing zones/farming spots - ding ding ding ding! This will be the meta.

The idea was that it was an equal battle ground. SS and TM offered the perfect distance for graveyards. Two teams could beat the hell out of eachother for hours. This is an archaic idea and will only be replicated by the casual audience/roleplayers. You can only kill the same player a few times before they stop yielding honor and you cant control a mass fight. Players may stop by if a big fight is going on, but they wont sit there and farm due to contribution points. When a player is killed the contribution points (value of the kill) is split between everyone who participated in the kill. More people = less contribution points ESPECIALLY when you are carrying 50-75% of the group who are just passively standing around and rolling hots or buffing to keep themselves earning CP.

Consider the 40 man raid that waits 20-30 mins to gank another 40 man raid and due to CP, its as if everyone on the team only earned the equivalent of 1 kill each because those 40 kills worth of CP are equally distributed between the participants. Worse yet, there wont be equal participation. So the mages, who hit everything, will yield far higher CP on average than a rogue. Raid vs Raid is not good for consistent honor farming and is a low tier strategy UNLESS you can win trade with a massive group of people. But remember, you are fighting for a bracket placemement. So the more people on your faction to participate in such a farm, just inflates your own competition for bracket placements. The honor grind is NOT about you VS the enemy faction, it is about you and your team VS your own faction.
Meta will probably be 3-5 man gank squads.

This will most likely be the case with few exceptions. We may see the king of thunderbluff kited down the hill and killed by teams. We will see 3-5 man gank squads farming unguarded areas like flight paths. These teams will move around the world targeting level 48-59 players.

At first there will not be a meta. The first two weeks will be chaos. The casual audience will get tuckered out and stop trying. You will be left with deathsquads farming the highest honor per hour they can find. Classic could shock us, but I would bet that the small deathball strategy will work best and will be used to steamroll lowbies that give honor.

You want to find poorly guarded areas that are also high traffic. Preferably questing hubs and preferably that wont have many 60's AND, when 60's inevitably come, you want them to have a decent travel distance so you want this place to be relatively isolated from main areas so that their response time is awful. A great place that comes to mind is marshall's refuge in Ungoro. No guards, high traffic quest hub for level 50's and a decent distance to any other major city or area. This means a death squad can easily farm ungoro for 30mins-1hour safely before a resistance begins to form and then quickly move over to the south corner of tanaris for a quick sweep before porting somewhere else. I think mages will be important for the honor grind because good teams will want to move regularly. I would be moving every 30 mins - 1 hour. You cant risk a fair fight / getting locked down. It tanks your honor per hour.
What I would do is setup a squad with 100% mounts and travel most farmed places in Felwood / Winterspring, without stopping in a place in particular.

Felwood isnt a bad spot because its very dense and its a funnel. The entire zone is one big tube. You can run right down the center and find any/all lowbies with relative ease. The Alliance flight master in particular is very unguarded.

Winterspring is a bit worse because everlook is well guarded AND the zone is incredibly spread out. It wont be very efficient to farm. I would only use winterspring/azshara as cool-off zones for felwood. If my team stirred up too many people in felwood and they began to group up and had any chance of beating us I would quickly move to a cool-off zone to continue the lowbie farm.

The idea is to continue moving as often as possible. You cant kill the same people too often or they stop rewarding honor. As soon as you lockdown a zone for 1-2 hours (this is often the entirety of a casual users play session) players will choose the path of least resistance and move - so you need to move too. Having a secondary account with a character on the opposite faction to /who 48-50 will give you a good idea of where the lowbies are at any given time so you can track their migration patterns and continue to gank the biggest herd. I would be using this tool AND moving every 30mins-1hour. While in a zone I would be tracking enemy 60's. Who is in the zone, who is new to the zone, etc etc etc... As soon as I see 4-5 showup, I would move.

What about Stranglethorn Vietnam?! But I agree most likely its gonna be Hillsbrad.

Lowbies are too low. They wont yield honor.

It’s quite ironic that farming honor in WoW is also the least honorable activity one can find in the game.

While I completly understand the min-maxing aspect of it and how ranks work I still find it rather repulsive

Yep. Its actually hilarious. And unlike some other activities, to adequately do the rank grind, you really do need to min/max because youre simply competing in a bracket against other players. If you want to reach the upper ranks, you need to min/max.
