Why is it, going into ShB, that BLMs are going to be the ONLY DPS class without some sort of self-heal?

All Melee and Physical Ranged have Second Wind. Melee also have Bloodbath.

RDM has Vercure.

SMN has Physick (pitiful as it is) and soon will have the Phoenix regen.

BLM has.... nothing.

At one point we did have Physick, and then we had Drain... no longer in ShB.

Why?
