I think the ideas for the game have improved, but the implementation of a lot of them has not. It's also significantly sad that we get less dungeons, and more boring dungeon designs from what's actually inside of the dungeons. Give me another problematic Pharos Sirius. Give me dungeon bosses with mechanics like the sandworm in Copperbell HM. Give us more than three bosses per dungeon while you're at it. And make dungeon bosses last longer too.

It'd also be nice to see more four man trials like the primals were in the MSQ back in ARR.
