Frankly there's a lot of BG3 that is already pretty close to my ideal CRPG.
So the things I'd wish to see addressed in a hypothetical BG4 are pretty much the same I'm currently hoping to see changed or improved in BG3.
A control scheme that doesn't make me wish for an armed conflict with Belgium in the near future, support for a larger cast, putting aside the fairly redundant idea of "origin characters", a world with day/night cycle and a sense of passing time not perpetually stuck at noon, a better and more flexible implementation of verticality, (like actual flight and climbing), some occasional tweak in terms of visual and aesthetic (I'd gladly do without the cartoony bits, for one) etc, etc, etc.
Maybe if we have to talk about big structural changes, I'd be all for having smaller individual areas connected by world map travel, so we could avoid the current sense of "diorama world" where everything feels fifteen meters away for anything else.
That aside, as a general direction, I don't think I'd be a big fan of an "epic level campaign" (from lvl 12 and going up) continuing where the predecessor will leave us.
I think I'd favor a fresh start with new characters, starting from low level and all the way up again.
Yeah I agree with all that, essentially. I would also add that I would love to see them implement a system where character story progression is not bound to long rests, but rather that it can happen along the journey. Maybe characters reacting to something in the environment sparks a scene or something.
