-No day/night/clock/weather.
-The awful party control system.
-Party locked after Act 1.
-Custom PC being a decidedly lesser experience than the tragic Origins system.
-No 6 person party.
-Theme park maps.
-MMO style loot.
-That Shove will continue to be an optimal battle strategy.
-The UI.
-Limited Companion choice.
-Continuation of comic-style, goofy animations (Super Mario jumping, Shove and missile trajectories).
-That the end game will run out of steam because of the explosive introduction and exposure to high level monsters and dangerous locations from more or less the outset.
-That it continues to deviate too far from D&D.

On a personal level I suppose my biggest concern is that I will never play the game once it is finally released because it more or less stays as it currently is, and I haven't touched the game since the end of 2020. I would genuinely love to be enticed back to this game, which is probably the only reason I have hung around these forums to see what, if anything, changes.
