[Quiet Man Cometh]

I wouldn't say I found balance to be an issue. I saw them more as different tools, to be blunt about it, that varied in usefullness depending on the situations. In BG I've never found myself wishing I had fewer of one type over the other, most of the time. I usually wanted 2 fighters, 2 mages, at least, and the other two were grab bag.

Never played a character in Morrowind that was only one way or the other so I couldn't say about that either. I suppose I could try that and see what happens. I like having acess to a mix of skills.
