Something that I would like to see for warriors is a change of their charging mechanics:
Arms Tree: Remove the cannot be used in combat from Charge, but can only be used in battle stance still.
Fury Tree: Move Imp Intercept back into the fury tree, but can only be used in berserker stance.
Protection Tree: Change Intervene so that we charge our target instead of the targets/target, but keep the rest of it the same.
That or just remove the fact that we lose almost all our rage from changing stances so we can utilize the proper charge without crippling our rage.
