Well, since it's all optional and it's a single player game.
The only bad thing is removing requirements for multiclassing (is it actually confirmed?) - it directly breaks the rules of 5E and actually takes AWAY from the game, imo. And also that bit about bonus spell slots which I didn't really get.
Instead of removing restrictions for multiclassing (which are STAT requirements), wouldn't it be more logical to roll for stats? Just let us spend 1 hour rerolling to get the perfect stats - our character would feel much more special.
As for Companion re-spec - it's a good option, what if someone hates Astarion, but needs a Rogue in their party? Make Shadowheart into a Rogue! Or you are dead set on RPing a Rogue yourself, but you are also interested in a monk very much - make Laezel a monk!
Part of the fun of Icewind Dale games was tailoring your own party. I did the same thing in latest Pathfinder games - used mods to re-spec the companions into the most synergetic parties possible.
But it's just an option - don't use it if you don't want to and keep everything Vanilla.
Almost nobody cares about the minimum stat removal. The clownery lies in boosting multiclassing well over the boundary of the absurd. It's not needed for sales the way easy mode + resets are. Nor, even ignoreable and optional like a magic, appearance changing mirror.
No, it's at *best* going to clutter my game up forever. *Realistically*, even force people to use that playstyle, because Larian ramped up the combat difficulty with these builds in mind. There is exactly nothing optional about it. You cannot opt out
