Destro Locks and Fire Mages need an immediate nerf, they are broken OP at the level of Taste for Blood Warriors in the beginning of WoD.
PvP balance at the moment would be more or less fine, unless these two grossly overtuned specs + Lightning Lasso spell and casting in wolf form + Resto Druids. These require dev attention.
There is literally nothing you can do vs. so much CC, survivability and damage mixed together as a melee unless you play Rogue. Well, speaking of Destro Locks, you can at least be lucky to sometimes catch them w/o CDs, but Fire Mages... God... having that insane mobility in addition to everything else mentioned above - I'd say they are way worse even.
Destro Locks need either their CC to be toned down, if they are going to keep this level of CB damage, or the CB itself nerfed if the CC is there to stay.
Affli should be buffed a bit so the spec becomes desirable. At the moment nearly no one is playing it.
Fire Mages need to lose some of their survival, they are supposed to be glass cannons with that much CC and damage potential AND mobility, they can't have it all.
Lightning Lasso + any casts in wolf form also have to go. This is ridiculously broken. Eles should get something more reasonable as compensation for lasso, which will keep them viable though.
Resto Druids should lose flat 10% healing on all their spells.
