A buff is a buff, glad theyre actively looking at and analyzing pvp.
Quite frankly most of their changes are terrible for Warriors at least.
They should look at buffing either Mortal Strikes base damage (its damage outside of CS is garbage, even with 3 stacks of FR), tactician proc rate in PvP or Overpower (it being inferior in both PvE and PvP isn't good, especially as its a well designed PvP ability).
Bladestorm needs to be a relevant damage CD again in PvP, hasn't been since MoP.
Charge Stun needs to return, anyone who's played Warrior for a long time knows that this is basically the core of Warrior PvP, the class just doesn't play the same at all. At least for me Charge Stun was largely what made Warrior PvP interesting and fun.
Changes like buffing Strength by 10% are just lazy.
