Combat system is beyond saving.

Well, you won't find me calling BG3 an mmorpg but it does prove that that kind of gameplay and game design is still very much revelant.
The issue is no major or even minor mmorpg has tried to replicate it as an mmorpg unfortunately.

Game designers have this belief that people don't have patience for more tactical gameplay; again BG3 proved them wrong.

I don't think it'd make for a good MMO though. Imagine waiting for 24 people to take turns.
