Yeah, they -are- changing all the LBs so each class has a unique looking one that makes sense for their class. However, they will be completely the same functionality wise.

So, instead of using the BLM's Meteor attack, SMNs might instead briefly summon a full primal that does their signature attack. Same damage and same size AoE as the current AoE LB, just now it is definitely a SMN limit break. I imagine a DRG will involve spears, and MNKs involve fists, but still does what their current LBs do.

So, yeah. BRDs will still heal. But hey, maybe they'll change it with the upcoming Gun Job since there'll be two ranged physical DPS?
