I didn't play DOS either, so I can't speak to that. I have to assume that core DOS is a lot like 5e, because BG3's gooey 5e center seems pretty evident to me. D20s affect the same stuff, add your proficiency and ability modifiers. The most radical change I've seen was done to the rogues. No expertise, which is something worth complaining about, but it doesn't ruin the game for me. Thieves gain an additional bonus action, as opposed to the stuff it gets in 5e. No sleight of hand bonus action. Again, worth speaking up about if it bothers you, but for me it's not a deal breaker. What am I missing?
Unlimited rest which defeats the point of short and long action resets. Backstab advantage just by attacking from behind. Everyone gets a bonus disengage/jump. Eating food for HP, even during combat. Surface effects for a lot of elemental spells and attacks. Dipping. Height advantage/disadvantage. Mages can learn any spell, including divine clerical spells. Tossing healing potions to heal others and creating a surface that heals. No real reactions as of yet and many are suspicious that we won't get it. There's a lot more but that's just from the top of my head.
You know why all these things are in the game? Because Larian likes extra actions for characters. They like surface effects. They like "cheese" as many have mentioned on this forum. And all this cheese came from DOS. Larian built BG3 on the DOS engine and migrated a bunch of the gameplay. So yeah, you roll d20 and have AC, HP and such that resembles 5e but the actual gameplay is a pale comparison to the tabletop version.
Mind you, no one is asking for a full faithful rendition of tabletop but there's a line where the homebrew overshadows the 5e ruleset as written. That's what is happening in BG3.
Look, you like BG3 as is. That's cool. But please understand that the players that have complaints about this game aren't doing it because they are bored or think the homebrews are minor. We all legitimately would like BG3 to be better and we are arguing that currently with all the Larian homebrew, the game is not as good as it can be.
