The problem isn't 5e, which while it has some strong effects is much more balanced than BG3 is. I don't even know that you can say the case is that Larian "wants things to be unbalanced and OP", by the way. If they do, they have a funny way of going about it since they actually *nerfed, rather heavily*, CC spells and made some CC effects much easier to get out of.

I also dispute that 5e is a "dumbed down and boring mess", having played 2nd, 3rd and 5th edition I think 5e is by far the superior one. The problem is that Larian's supposed "Do crazy shit and laugh about it" is what seems dumbed down and boring to me. In normal 5e, as a caster, I try to choose carefully what spell is best for a given situation, keeping in mind that I have to conserve my resources. In BG3, due to absurd itemization, it feels stupid to cast anything other than MM much of the time and conserving resources doesn't matter because you can just rest whenever you want. THAT seems dumbed down and boring to me. Having absurdly powerful legendaries handed out like candy seems dumb and boring to me. (And honestly, I don't even mind that you can cheese a legendary out of an encounter in the first act! It's about how powerful ALL THE OTHER ITEMS start getting, too.) Being able to stack a bunch of extra damage rolls on top of melee attacks, completely unbalancing them, seems dumb and boring to me. *Combat without challenge, and no consequences for burning through all your resources, seems dumb and boring to me.* And that is not 5e, that is ONE HUNDRED PERCENT down to the choices and changes Larian made in this game.

And again I don't even think Larian is actually aiming for "do crazy shit and laugh about it!" If they were, why did they nerf CC? Why are they pushing casters towards simple "unga bunga do the big numbers" casting, rather than letting them play around with the myriad effects they have available to them?
