Why is BLM getting a buff?

[Sleigh]

Except weapon, all the gear are shared between Blm and Smn. why not people just play both class and use Smn for single, Blm for AoE. Then you would end up being good at both.

I don't see why Blm people need to be only Blm.

Weapons as of right now. It's a heavy investment to either get an Animus or spend 1300 tomes + sand + tomestone to get the i100/i110 weapon. Since i110 weapons are such a huge upgrade over i95/i100, once you buy a weapon you're basically locked in that class efficiency wise until you obtain another weapon somehow.

Weapons, and people like to play different classes so you have different gear priorities (not fun to have the same ideal BiS as other people in your static), play styles, and in this case, it can be nice to have the on demand burst and AoE of a BLM, even if in current raids those aren't needed in the slightest.
