Yeah I don't really understand the idea of "its not optimal so it shouldn't be in the game"
I mean yeah not every combination is gonna be all thats cracked up to be and you can end up being underpowered but thats a part of the fun with multiclassing, sure it can backfire but it makes it all the more fun when you find a combination that works or has just fun synergy especially when combined with things like feats and magic items. I mean at most all you have to do is just have small warning before you add that level into another class like "hey shit might get weird do it at your own risk"
