Umm... BLM isn't "supposed to be" close to any Melee DPS in damage. The heirarchy goes:

Melee DPS = King of damage
Caster DPS = Queen of damage
Ranged DPS = Joker of damage

This is due to required positioning, distance and skill/spell times.

Now, I haven't tested it, but if BLM is doing significantly less damage than RDM, then they should be buffed to RDM levels, yes. But BLM should most definitely not be at SAM levels.
