I've only got 2 stance keybinds, and you only need 2 in my opinion.
1. Most Defensive available stance
2. Most Aggressive available stance
I have most defensive on mouse wheel down, most aggressive on mouse wheel up! Works great for me
I do quite a different approach, very similar to macros but does not use em, back from time on playing on multiple servers and not always macros working the same.
I use 5 for overpowering while I am in battle stance, and remembering 5 to be the overpower it doesn't matter if I press it once or twice in any stance. This button became my battle stance button in any other stance since this is the biggest reason for switching mid-fight to battle.
Same goes for same button for zerker stance and zerker rage, since while tanking I double press it to go to zerker to stance-dance
And finaly same goes for defensive stance and bind I use for disarm, since if I am in any other stance main reason for going to defense is disarm.
ctrl c, ctrl v are normal
tap the 1 - 2 or 2 - 3
like you said C and V feel klunky the 1 and 2 feel klunkier than the 2 and 3
