Its subjective ...
Some people claims it makes game unbareable, others just shrug and go on.
It depends a lot on how do you play.
As far as i know, in lot (not all tho) situations, you can quite easily start conversations with any of your companions ... so if you feel like this situation will be hot and you should use someone with at least *some* skills in diplomacy, you can send there Wyll (or ... well, i gues thats it, i dont think any other companion have high Charisma
) ...
But as long as you play your charcter only, you simply have come to therms that some of your rolls will fail, even tho there is expert standing right next to you. :-/
