As a MCH main I kinda understand where you're coming from, this tier especially I've been told numerous times to switch off MCH to play DNC (never BRD mind you, which is the actual "meta" pick) both jokingly (which gets old and annoying) and in serious static situations. MCH isn't in a great place, neither is BLM. While BLM can deal damage tantamount to a melee even now, it's still not where it deserves to be.

Because of the complexity of the job I genuinely think BLM should be one of the highest damage dealers, and definitely far ahead of Picto who has oodles and oodles of party utility.

I think for the most part the balancing on this game is decent, for an MMO. But there are a few outliers that really need some love right about now... :c
