6. Whirlwind in conjunction with sweeping strikes currently uses limitless charges of the buff, depending on how many mobs are hit by whirlewind.
--> Instead it should always only use one charge of the sweeping strikes buff which leads to following case:
I hit A, B and C for 250 with Whirlewind, I hit B for 250 with sweeping strikes
judging from combat logs it looks like every whirlwind hit gets doubled, can't reproduce that though since I don't have a warrior
