I couldn’t agree more. And as EA testers it’s impossible to judge whether their “improvements” are necessary or not because we don’t get to try it any other way.
You can just play Solasta and have a perfectly working combat system that is (at least for me) about 10 times more fun than BG.
So yeah, for me, all that tweaking and half baked homebrew messing with the rules is completely unneccessary.
D&D 5e was developed with a lot of playtesting and an amazing humility from the game designers who listened to the community.
Larian clearly wanted to do "their thing", which is essentially DOS 2. I get it, they have their flair and their style. But the thing is; if they would have just started by implementing things well and true to the core rules, it would have been easier to start tweaking from that position. Actually, many of their stuff could have been made to fit far better even following the 5e rules, to be honest. Now it just feels like they're aimlessly changing things and it's spiralled out of their control. Too much homebrewing and changing a few things here and there until everything kind of ... is a mess.
