And that's their prerogative. That doesn't however, erase issues that they are creating.
Still, a bad adaptation is still a bad adaptation. Larian doesn't want to make table-top simulator but a good computer game? Good, fix your game then. Bad mechanics and balance problems remain just that, no matter what were the reasons for their creation. I don't think that many of us would care about how BG3 compares to 5e (though I am sure some still would), if it worked.
I think you will also find quite a bit of inconsistency as to when Larian thinks that BG3 should feel like a tabletop dice game, and when it shouldn't. If there is one thing I am not entirely conviced about is that if Larian has defined, focused vision. BG3 seems to me to be all over the place.
I agree it's all over the place because it seems they have used difference sources as a base for their game and just like mashed it all together.
