Not only that, but the further BG3 strays from 5e, the more fallout there may be. We have seen this not too long ago with Cyberpunk and the hate-train, where people turned on CDPR because they "lied" and made "false promises". Regardless of it being true or not, it was blown out of proportions and people just jumped on the hate train because they could.
BG3 already has a hard road ahead of it, with how there are already plenty of people hating on the game for not being a true BG and not a worthy successor etc. With how Larian promised a game "As faithful to 5e as possible" with options of being able to make your 5e character in BG3 it makes the situation even more tricky with deviating from it. Regardless of what you think of Solasta: Crown of the Magister or BG3, Solasta did prove that you can be really faithful and making a game with solid mechanics, adding to it being a tricky situation with claims of being as faithful to 5e as possible.
It is a hate-train bound to happen, much like it happened with Cyberpunk2077 and CDPR, and that is something that should not really have a repeat (It was kind of ridicilous how such a thing happened in the first place as well but that is a different subject).
I find myself wanting to quote this and highlight it again, because this is a legitimate, real-world consideration that goes well outside the game itself, and it's a real and genuine danger that Larian should be actively aware of and considering. These are important factors that will come into play the closer the game gets to release.
This is a much beloved franchise, and Larian have made certain promises and certain claims about it; the situation is decidedly volatile. The studio making claims about making a game as true to 5e as they can, but then diverging so much, while a parallel game makes a very faithful rendition that works well, is going to risk major backlash; upselling with claims about how you'll be able to make your favourite D&D characters in their game, when the ruleset is so divergent that you realistically will not be able to is only going to make it worse.
They really need to be more careful about what they promise their audiences, or they need to deliver on those promises... otherwise it won't matter how fun or enjoyable the game itself, independent of any other consideration, might be - it will get torn apart and flop miserably. The have to be aware of that danger and consider it seriously.
