Err ... Biowares crucial fault was that they wanted to create a MMORPG - "The Old Republic" - but didnt have the necessary funding, so they sold themselves to EA.
Comparing pre-EA and post-EA Bioware with each other is invalid because post-EA isnt an independent company anymore. In fact its now nothing but a brand name. EA simply named all their development studios Bioware, to profit from the good name of pre-EA Bioware.
To make matters even worse, a storyfocused MMORPG turned out to be not such a great idea in the first place. So the success of TOR wasnt even that big.
Anyway, that and nothing else is the reason why Bioware is no more. There is only EA. Greedy, greedy EA.
I guess there is indeed a chance that BG3 will stay Larians most popular and successful game ever. Because of the added value from D&D.
People dislike the round based logic, the spells per day limitation, the simplistic armor class and hitpoints, and the other issues that are all caused by the fact that D&D is designed primarily for pen and paper, not for computer games, and thus has to keep all computations on the most simple level possible.
But despite these design constraints, D&D has a lot of depth and complexity to it, and a lot of decently developed lore in its settings, too.
Designing game rulesystems that work well isnt that easy, even if many people seem to be gloriously ignorant about this problem. On the one hand you want to give the player the flexibility to create an unique character, on the other hand you want the game to be balanced. This is not an easy problem to solve at all.
