The problem I have with all of this is
You can multiclass in this game.
I found a couple items which gave +intelligence and +sneak, or staves which gave +perception. So I decided to give them all to one of my mages and make them my scout as well. Any time I needed to sneak or spot traps I would send her ahead. By the end of the game she had +5 perception and +3 sneak from equipment, and still wound up with more than 20 intelligence.
You can have your man-at-arms use bows. You can have your Ranger use two-handed swords. I like the fact that there is equipment which has peculiar stat combinations - it opens up the possibility of multiclassing, which might have been too difficult otherwise.
