I see this complaint a lot but I've yet to hear a good explanation for why it's actually a bad idea beyond "5e handles it this way instead". There's nothing special about hp, ac, and vancian spellcasting that gets ruined by BG3's implentation of the rules. Numbers can be tuned to account for the added functionalities of some spells and the rest is just adjusting available resources. It's bizarre that "It's not the same as it is in 5e" is a reply to "I find it fun".
You didn't hear a good explanation? That was literally the explanation. It's not difficult to understand.
Here, there's a part that I left out.
EDIT: There's more. Some spells target AC, other spells require the target to make saving throws. The spells which target AC are easier to hit because of lowered monster AC. Saving throws have not been altered. This means spells which require saving throws have not been rebalanced and are now underwhelming to use and are not effective. See Sacred Flame, Color Spray, Sleep - all of those feel very bad to use because they're much more ineffective than they should be. Other spells are powerful because they require Concentration to be effective. Concentration is a saving throw. Saving throws are much easier to fail when there is unresistable, no-saving-throw-to-avoid damage and AoE attacks and explosions all over the place. This makes concentration spells less effective, AND LESS FUN TO USE.
The game is using two different systems designed for two different styles of game. Because the systems are working at odds with each other, THIS DOES NOT FEEL FUN.I hope you are able to understand that.
No problem with having to make adjustments when it comes to making this a PC game. But there are adjustments and there are just bad homebrews. If we are honest 90% of homebrew is utter shite, because people are not thinking straight, but "omg having a heavy armor wizard subclass with access to 9th level spells as their starting ability would be so great" (overexaggeration, but you get the point). Similar I feel that Larian is going hard for their revamping of mechanics like surfaces etc. They make concentration spells basically useless, and those already are a gamble in the normal rules. Just to point out one huge problem.
This. There are plenty of adjustments from the tabletop which are good and fun. Because some things need adjusting does not mean that every single adjustment is by definition a good one.
