Id be happy with just a bonus 600 mana and maybe 15 secs on the astral/umbra since its a very tight fit for 6 f4's in normal rotation without any ogcd's. You know, 2 seconds for leeway movement. It's not a huge buff but it'd get your rotation out without waiting for the tick before you start F3(which i never do) and a big QoL upgrade overall. Other than these two, BLM feels fine overall. The damage on black mage is fine imo. So far in the story mode raids I sit at 4.2k+ dps on v1/4 and I don't think it really needs to be higher than that. I'm sure some samurai's beat me but we're supposed to be second to samurai because we have the benefit of range. That's just my 2 cents
