It’s much easier to balance the game around 3 pure class predetermined companions than around the idea of 3 fully customized optimized build multiclassed ones .
In short Withers is 100% a gameplay feature not a Qol feature
If any fight can be won with a solo super build why does it matter what can be done with companions?
I agree with your point that Withers is a large advantage to the player, but I also can see how having the ability to re spec allows a player to experiment and learn the game more quickly. This, in fact, makes Withers a QOL feature. I mean if I had to play a new game to experience every build combination it would be pretty stifling to my game QOL.
It would be nice if Withers was a setting.
