Once you get to blm you loose the cross class heal of conjurer.
Instead you can have Physic to heal yourself which is from the Arcanist class.
I highly recommend any blm get Quelling Strikes from Archer as it is so easy to get agro as a blm, QS reduces that
I started as a Archer as my Main class so i already had that portion unlocked and Bard is a fun class as well. But blm by far is one of the more damaging dps classes.
