Baldur's Gate 3 is great at story and choices, which I think is where a lot of praise comes from. But it has a lot of really questionable issues with smaller mechanics.
The one I'm hating the most is how NPCs react to many summons and wild shape. Having a wild shaped party member makes most NPCs run away screaming, which is very painful in the NPC heavy areas of act 3 and basically discouraged you from even using wild shape or summon elemental, even though those are both incredibly powerful. You can dismiss the summon/wild shape, but it uses resources, so it sucks to do so. People have reported the bug for months but it doesn't seem on the devs radar (they purposefully made NPCs run away -- it's a "feature").
And just the other day, I discovered weirdness with warlock spell slots. Something about having used an elixer that gives me an extra spell slot (and then having consumed the spell slot) was preventing me from casting certain warlock spells (I think those of the spell slot's level) because it claimed it needed that spell slot, even though I had higher level warlock spell slots. So a bunch of my spells couldn't be used! When I searched, I found many reports about similar issues when people multi classed.
