As i said in another thread (but it belongs here better), i really hope at least for multiplayer they give us easy way to have more than 4 characters. I usually play solo, but when i do play with friends it can easily exceed 4 character limit so some of us can't play with others. Making party cap soft cap instead of hard cap would be fantastic, i think if you could toggle it as option with disclaimer that it may mess with balance and cause unexpected issues it would be fine. Even less polished experience with some issues here and there but with everyone being able to participate is more enjoyable than splitting the group or some of us not playing.

other:
-Less gear tiers and bloat than in DOS2. Makes each piece more meaningful and less micromanagement, small stat differences should instead be done by runes and other player controllable things, not counting legendary unique gear and such
-While generic stuff can vary in quality and stats as game progresses, truly legendary unique piece of gear should remain legendary even in late game.
-More visual armor/outfit customisation options
-Ability to pre-plan my max level character in-game
-Less floor is lava compared to DOS2
-Less missing in combat than in BG3
-More detailed quest log to record important previously done choices better. Game is long, its really difficult to remember every decision.
