Why would anyone choose BLM for anything now? If nothing changes (Which has such a high chance of happening):
SMN has currently an 80% buff to their raidwide damage buff
RDM has a ~30-40% increase to theirs.
SMN then gets a free to use Manaward, TWICE. ON HALF THE COOLDOWN. WHAT?
SMN can now move close to 100% of the time without DPS loss, even without having Ruin 2 for movement.
RDM now has a damage reduction AND healing increase cooldown
What does BLM get? We get a free Xeno every 2 minutes, slightly increased damage in place of Fire, reduced Convert cd and another sharpcast. That's it for single target. It's a whole load of nothing in comparison!
Meanwhile we also get a nerfed Xeno for some reason, while the one thing we need to counteract SMN/RDM buffs is MORE damage.
We have lost one unique utility we had, which was Manaward. SMN technically had this with Titan-egi before, but no one used that as it did less damage. Now SMN can just use a 20% Manaward twice in the time we can do it once. Ours is actually worse now since we can only do 30% in 2 minutes, while SMN can do 40% in that time.
BLM still has no ability to raise, which is STILL the primary reason no progression group will ever accept a BLM into their party if a SMN/RDM of equal skill is available. SE has already shown they don't care about integrity of other jobs, so adding raise to BLM to keep it fair between casters MAKES SENSE.
Currently, BLM has had barely any buff to damage. Many jobs have gotten very slightly nerfed on potencies, but for BLM to even stand a chance against SMN/RDM with their non-DPS utility, BLM needs to be dealing over 25% more personal DPS just to outweigh these advantages. SE has never been able to understand how to balance casters, but they keep being completely oblivious to what's causing this to happen.
What I think should rather be done, RDM/SMN should get rid of their non-DPS utility and get rid of their raises. It makes just as little sense for SMN/RDM to have it now as it does for BLM to have it. It doesn't destroy the jobs, it would also even balance out casters much more with melee/ranged, as currently casters are taking over the 2nd melee slot more often than not. Why would you ever pick a 2nd melee, when SMN can move anywhere while dealing all the damage they can, give raid buffs, raise people and shield themselves? Answer: You wouldn't. The balance between the casters will be destroyed with the next expansion if nothing changes.
First step for Square Enix to fix this issue:
REMOVE RAISE ON SUMMONER AND RED MAGE.
