I think that’s right, from memory as I’m not at my PC.
There’s also a case for a button that switches your stance and casts a spell at the same time (they have separate GCDs so one press will fire them both).
/cast Battle Stance
/cast Overpower
You’ll need separate buttons for your spells though as they will change your stance.
what this should do is, if you are in Def stance it will cast revenge. If you are in berserker stance it will move you to battle stance and then cast Overpower and if you are in Battle stance it will just cast overpower. It will also show you the Revenge tooltip while in Def stance and show the Overpower tooltip in Battle or Berserker stance.
lol didn’t stumble across this thread until a day or two ago when i was looking for the same thing. couldn’t find one that did what i wanted so i wrote one myself. Not really knowing how though it took me about 30 min or so. figured i’d share what i came up with incase others were searching too.
