-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.
