Something else about stances.
I usually don't put them directly on my hotbar, I use bongo's primarily, and just use shift 1 (!) for battle, shift 2 (@) for defensive and shift 3 (#) for zerker. I haven't had my hand cramp all that much up either from using ctrl alt and shift for single hand operation.
But i used to use something like the below setup before I found bongo's.
something like
1 2 3 4
q w e r
a s d f
shft z x c v
spacebar
1; battle stance
2; defensive
3; 'zerker
4; battle shout
q; charge/intercept macro
w; MS
e; Hamstring
r; piercing howl
a; sidestep left
s; move forward
d; sidestep right
f; target announce macro
z; target last target
x; walk backwards
c; target next target
v; spell reflect macro
shift; team speak/vent toggle
space; target announce macro
A side note or two. Having a good stable vent server makes target announcing slightly easier. But I've played with many people who lack headsets and the $20+ dollars to to get a decent one worth buying. Having a headset that doesn't make pop/zing/hiss noises will make your teammates not want you to die so often.
using a target announce macro helps, but isn't necessary. I also made a bunch of /yells that where funny to make the opposing team read them and stall a little, maybe laugh. Don't know if it helped, haven't played serious pvp in months (eve is currently pwning my game addiction), but I sure felt better after spamming a short yell macro, I felt pretty good at least knowing they felt 'something' after outright murdering me and my team. Since I was in a strict PvE guild for long enough, I didn't have time to PvP alot, and thus was in PvE gear doing PvP, with a PvE spec... Just like everyone else on my team.
If not for your daddy, you would be a naked filthy bureaucrat who dines alongside the vindictive cannibal and the rotting piglet.
Thine sister is a toilet-bowl licking yodeling chicken molester who gripes about the good for nothing piglet and the ************ fanatic.
Quit being so stupid, you fascist pathetic piece of crap who has delusions about being the reeking piece of crap and the illiterate clansman.
Thine sister is a ragged smelly crotched freak who dines alongside the dweeby disease and the whoring nutcase.
You will die a vain snot loving snotbox who munches on the necropheliac penguin groper and the brain dead douchebag.
You are no better than a belligerent cursed fruit basket who worships the miserable hag and the psychotic corpse.
The world is against you because you are a nipply mangled penguin groper who scares the war-mongering salad for brains and the decomposing virus.
You aspire to be a nipply necropheliac donkey who is obsessed with the two bit dip **** and the stinking bottom feeder.
Your occupation is a whoring immoral jerk-off who jumps the raving bird brain and the scaly eunuch.
You regurgitate your food and eat it, you armpit smelling desperate crackhead who is the child of the the raving slob and the godforsaken worm.
