The way I see see it is affliction suffers dps-wise because it incurs a much larger penalty than any other spec/class from mobile boss encounters. Losing haunt on a target cripples our dps for two rotations while every other class can pick up dpsing without any loss. Cant say I wouldnt mind it if we did get a 15% damage increase on every dot but it isnt necessary. The only thing affliction needs is an increase to burst for pvp... which should come from new shadowbolt talents placed in the affliction tree (maybe even a haunt increase as well)
