The DPS queues at cap are pretty wild, well over an hour on Primal, I don't think seen anything quite that bad and I've been playing MMOs since Ultima Online.
Despite that, I'm not really surprised. Red Mage and Samurai are extremely fun and Tanks/Healers didn't really get much exciting. The only bit that confuses me is that I've seen more whining about AST and PLD than actually asking for QoL passes on the rest. That is Blizzard style design, nerfing things that are largely fine to make the worse off look better. You don't want that.
I still lament that we got a combat system revamp and Red Mage without any hybrids or alt-specs added. I would love to be able to heal on a Red Mage, well outside of failing PUGs, that is. But, I always wished the same thing for Bard, Summoner, etc. My only big dislike in XIV remains the WotLK-esque enforcement of pure roles when XI set a good standard for hybrids.
Realistically though, at the minimum if they insist on keeping baseline classes, they may wanna find a way to start tossing multiple jobs onto more than just Arcanist. At least then they'd hold more of a purpose and people hitting cap wouldn't just have one role available.
