@7d7 ...
Question: Presuming this suggestion would be implemented ... what exactly would be stoping you from taking none and play exactly as you want? O_o
Presumably the game. I don't think you can just not select features (feats or class abilities or ASIs) when you level up in BG3, unless I'm mistaken(?). I suppose you could take a useless feat, but that's definitely not the same.
Coming from 3.x, 5e feels really bland being so stingy with feats. I think coupling feats with ability score increases was a really bad design choice. Having to choose between feat or ASI is not a fun choice and feats are great at making PC's feel unique, also mechanically.
I'm fully expecting WotC to fix this mistake in the next edition of D&D. And in the meantime, BG3 could have it's own house rule. The level-ups where you don't get to make any choices and just wait for "accept" to become active are really meh in BG3. So perhaps even ASI's should be spread out more to +1 every two levels. That would already give you a choice on level 2 which is now really lackluster for many classes. Then a feat at level 3 like in previous editions... at least one choice per level up.
+1
I like the idea of getting a +1 every 2 levels instead of +2 every 4 levels, although that's a very minor improvement.
A feat at level 3 isn't necessary imo, as that's a big level for practically all classes. You choose your subclass and/or get 2nd level spells (along with a
doubling of spell slots). Especially in a system where we get +1 ASI every 2 levels, I'd put a feat choice at levels 1, 4, and 8 (the current ASI levels).
