Flurry is a talent that activates when you crit with a melee attack, and increases your attack speed.
It works most of the time, but I've noticed that whenever you crit while you have one flurry stack remaining, instead of refreshing all of your charges, the flurry buff just goes away.
I do not think this is intended as if you crit twice in a row your flurry stacks stay at 3, and if you crit with 2 stacks of flurry on you it resets to 3.
I'm posting it in the general forums because I'm a shaman, and I know that warriors also have the Flurry talent, not sure if they're affected in this way though.
I assume more shaman haven't reported on this as they mostly use windfury, and just assume they didn't see the numbers in the proper order.
