I assumed when that '4 of 6 skill groups were magic' thing was mentioned that the other two groups were something like combat and non-combat, which would cover everything else. It's good to know there are enough skills now that that wouldn't be a practical way to organize them, if that was every the intent.
I mentioned the possibly of playing a mage because turn based combat eliminates some of the reasons I usually don't play mages, not because I thought the game would be focused on magic.
