Well, they apparently thought BLM was really underpowered because it got an absurd number of buffs in the hotfix patch. Their overall damage output and survivability is considerably higher then it was before now, especially during LB thanks to Flare/Freeze getting a 50% potency increase and getting 15 seconds of 20% damage reduction while it's active to boot.

They also added damage mitigation to GNB LB and Honing Dance to make them a little safer to use, though I still would've preferred being able to use purify/recuperate while they're active.
