I don't see how anyone sane still has any kind of hope for BG3 to be a reasonably faithful rendition of the rules, not after that last stream. Larian basically had Jeremy Crawford there for the sole reason of telling you rule-lovin' nerds to f**k off, LOL!

Don't get me wrong, I feel for you, guys & gals, I also have the 2nd, 3rd and 5th edition PHBs in my library, but it is rather obvious that it IS going to be this Larian's jumpy, cartoony, DOS-like combat system with dipping, barrels, eating stuff during combat (there is still some little hope that this might go away, but...) and (basically) misty-stepping badgers. The best we can hope for is that the future updates (though patch 4 is not going to fix anything, if I understand correctly) are going to at least fix the combat a bit so it does not suck as much and becomes at least a bit more tactical and encounter-specific (rather than the optimal strategy being abusing the same OP aspects almost every time). The dumbest scenario I'm afraid of right now is Larian keeping the current system BUT refusing to change/rebalance most spells/abilities to reflect the fact that this is in fact not 5e - that would be really dumb, rendering a huge chunk of spells/abilities useless and another chunk OP. If Larian clearly cannot let go of the DOS combat system fundamentals, they should just change everything to make it at least more-or-less as enjoyable as those games.
