As the title states, they could do something very minor and help fix the class as a whole in pvp, intrigued ?
consider that whatever spell cataclysm becomes after they finish re-working it ,turns out being successful in what it's design is meant for it to achieve, but why only favor destruction ? that very spell (supposing it will be useful to grant casting windows or another form of CC) can be used for all other specs too, if they should give it to warlocks as a baseline spell for all 3 specs this should somewhat negate most of the problems , if not significantly reduce the problems as a whole for warlocks in pvp.
if the spell costs an ember it could cost a shard/ fury for the other specs, or just mana for all of them.
I don't see why destruction has to be favored in that aspect where other specs ( mainly affliction) is the one in need of help the most.
it's not that big of a deal in my opinion since they're already adding that new spell anyways, thoughts?
