Mechanically, I think most are fine, in terms of what they "should" be, though... IDK, Bard or Summoner?

I'll probably go for Bard for now, since Summoner is getting Egi-Glamours eventually and that might change my opinion of the Job... I want Summoner to actually spend its time summoning (specifically, I like the idea Dreadwyrm Trance introduced, having a rotation that takes you through Inferno Trance, Vortex Trance, and so on would be much better than pets IMO), by it is very Final Fantasy to pick a favorite summon and just stick to using that over and over...

Bard though... Ugh... I don't mind the bow, what I hate is the utter lack of Songs... I think it suffers from a broader problem with Jobs in this game in general, specifically the rule of three we have, along with things like dungeon design just being lazy... Things like crowd control being worthless in a boss fight I'm fine with, the strength of things like Sleep always came from the random encounters, but SE does nothing with the trash mobs in dungeons and they do nothing with the layout of dungeons... Ideally I'd like a situation where multiple routes are available, and which you pick is based on what Jobs you have. So perhaps you have a Black Mage or Bard (with a Sleep Song), so you go one route because you can crowd control the trash rather than fighting and skip them. Another run you have a Ninja, so you have them sneak off to grab a key or something... Variety like that is sorely missing in this game...

I think what made Bard worse was Heavensward... Machinist I'm fine having Gauss Barrel, that kinda makes sense, even if the animation doesn't. Wanderer's Minuet though? Why do these two Jobs need the exact same mechanic? That is just pathetic... New level cap, perfect chance to give Bard some more Songs, best we get is Warden's Paean... Granted, that's much better now than it was at launch, but... Ugh... Where are the Songs?
