I'm a BRD main and I agree that BLM does need some love. I'm in the one comp that would prefer if I was something else. My co-dps are NIN/RDM/BLM, and Foes/crit simply isn't enough for them. SMN's Contagion alone would be far better for both of our casters if I swapped to it. The problem is this is such a niche comp to begin with that it's hard to tell if it's even worth it compared to the ideal comp that is DRG/NIN/MCH/BRD. I don't think standard raid utility's the way to go about it. Something like MNK's Brotherhood would be better for BLM. Or giving a weaker Enochian effect to allies while you maintain it. Like Foes, but constant.

I'd love to see fire IV's potency increased and its cast time reduced to 2.5s too. Currently the old ARR rotation isn't a big hit to your dps for the flexibility it gains while you're learning a fight. You can do a good chunk of prog with BLM by simply swapping to that rotation once new things hit you. I'd like for that to remain, but using Fire IV to its fullest extent should be encouraged more by buffing it.
