I can see them leaving at least the 2 piece bonus as it is and forcing us into the fire of justice talent. The reasons could be that we did ask for at least one proc and some kind of additional control over how we can use our proccs (read engaging gameplay). Oh and would be an easy way out for them.
Don´t understand me wrong I would really like to see the set bonus in our game play but please as baseline just like the procc itself and should that be deemed to good for us, the stack mechanic build into the procc.
What I find interesting currently on live is that even with 1:30 straight wings we can´t pull even to other classes on a 2 minute fight. Keep that in mind and remember blizz telling us that we will be fine in the burst niche.
