Why is BLM getting a buff?

[Alistaire]

I think melee are afraid to lose out to "blm onry" please.

BLM seriously lacks in single target dps when compared to everyone else. Yes, their AOE is superior, but how often in boss fights is AoE the make or break? Not very many. (T5 it helps, but it's not necessary for example) There's nothing wrong with giving blm's more damage single target. If anything this has been a long time coming.

They did say it's not just BLM they're adjusting.
