Well after two years of XIV:ARR, I can say that there were these 4 to 5 rare occasions where BRD LB3 Raise helped finishing the duty.

So why not have

BRD LB1 = dmg
BRD LB2 = dmg
BRD LB3 => choice between dmg and Raise

Don't ask me how this could be technically implemented tho. Maybe let BRD (or support classes in general) have two different LB icons.

(Yeah I'm repeating myself but who gives a shit)
