Quit after, as my friends all went to Xbox(Halo, Gears of war, CoD).
I was playing Horde on Burning Blade NA-PVP from 2005 on for the most part. I did play on Archimonde NA-PVP briefly when they offered free transfers there but ending up going back to Burning Blade. I did not raid much but when I did it was with Infallible on Burning Blade and New Dawn on Archimonde.
I had forgotten about the server transfers... I moved to/from Archimonde (I honestly can't remember which) with my guild when they had transfers but I can't remember the guild name or the other server name for the life of me.
I played on Burning Legion Alliance NA-PvP as a rogue in Vanilla. I don't remember the name of the beta server I played on before then.
US-Hellscream
Started out as Alliance on Kor'Gall EU PvP in 2005. Moved to The Maelstrom in 2007 when they opened up free transfers due to high server population.
I think i played exclusively on Sen'Jin during Vanilla, TBC, and Wrath.
I jumped around a lot between servers, although my main was on bloodscalp - eu
Darksorrow and Frostwhisper both EU PVP servers
Played on Zenedar EU as an Alliance priest. No more than through TBC though
Frostwolf and Lightninghoof
Burning Legion US Alliance as an Gnome Rogue
Ragnaros EU.
It used to be a balanced A/H PVP server but ever since they provided the alliance with a free migration across the battle group, it turned to utter shit.
Anyone with Alliance still on that server has to suffer toxicity from Horde players because of Blizzard's stupidity.
All just a Legitimate con to convince people to pay for character transfer...
I have however also played privately on Emerald dream. Kronos 2 + 3, Elysium, and Lights Hope.
Played a Night Elf hunter on Kul Tiras (EU PvE).
