What I'd like is more crucial skills showing up earlier, but maybe traits at later levels open up functionality, increase effectiveness, reduce CD, etc. That is actually what a lot of traits already do; PLD gets instant spells, for instance. I don't think they have to make all of everyone's kit available at a low level, though they can probably improve the gameplay experience by making stuff that feel super core to the job experience available a little sooner. It's said a lot but The Black Night should show up sooner, but maybe has a longer CD until you get a trait at 70. Little balance levers like that.
