BLM needs some love and RDM needs a nerf
Fire IV needs to be buffed back to 280 potency to even compete with RDM in damage, and then we're still far away from SAM in damage, which is where BLM is supposed to be.
Blizzard IV is a straight DPS loss if you have Foul available in Umbral Ice. Getting two extra Fire IV isn't worth the cast of Blizzard IV, and it's only worthwhile when Foul isn't available.
BLM still has no utility, but gets beaten by all jobs on single-target damage (the only type of damage which matters) except for DRG, BRD and MCH.
RDM needs a nerf. It has the most utility out of the 3 casters, but deals the most damage consistently and has the most movement. Looking at the SSS training dummies, it is supposed to be furthest behind. This is nowhere near the case right now, as it beats BLM and significantly beats SMN.
If BLM isn't doing the most damage ahead of SMN in 2nd and RDM in 3rd when Savage releases, then BLM isn't viable as SMN and RDM will always have their utility to make them viable.
