What I'd really like to see more of with BLM is a mobility rework. As fights get increasingly unforgiving with regards to dodging various this and thats, the BLM suffers accordingly (not to mention "stack the whole squad" mechanics such as Titan EX, which by default force you to be a melee DPS ...) - Scathe doesn't cut the mustard and you are all too often compelled to prioritise avoidance to the point of losing your spell (and DPS). SMN are in this boat too, but worst case for them is a dot drops off (which may not even mean anything if it is restored before the next server tick) while BLM have to worry about the short duration of Astral Fire stacks.

Could be I need to get better at my class perhaps (I probably do, I'm sure I'm not the top BLM in the realm ...) but part of it is definitely the class itself; I am reading reports that top Final Coil statics are actually going 3 melee + BRD and benching the caster DPS roles, and I can only guess the mobility conundrum is a top reason.
