For me, with the direction that Larian has gone, and is hellbent on continuing, I doubt I'll even attempt to play the game in full after release if the combat remains centered around height/broken stealth/push/elemental surfaces unless someone puts a mod together to remedy the DOS tropes.
There's already mods that fix this stuff so that mod isn't even a case of when, it's a case of when will it be polished enough for you?
Yet to see a mod that fixes:
Jump/disengage spam
Height giving 'Advantage'
Fire/ice/poison AOE surface spam
Push spam
Barralmancy
Backstab
Stealth abuse
Dipping spam
Monster stat/ability deviation
Lack of readied action
It's not about "polish" it's about Larian deciding to start with DOS as a framework to try and create a 5E DnD game, being confused by 5E and deciding to just cram more DOS mechanics into the game rather than try to actually adapt 5E like Swen stated Larian was going to do when they announced BG3.
