Well, thinking on this again, if the game has a big a focus on magic combos as the gameplay demos suggest, it might not be a bad thing to make magic extra powerful. If melee/ranged damage requires you to split your attribute points, but not so much your skill points, maybe it's a kind of balance if magic is the opposite - you need to split your skill points, but not your attribute points.
Seven attribute points does sound a bit scary, but if it's what the game needs, it's what the game needs. You could bump that initial build of 30 free points up to +35 (or the 15 free up to +18), or if seven is just too scary, maybe find a way to remove one of the other 6 (Constitution) and spread its uses to other attributes.
I also hope that this game will let +attribute bonuses from items exceed the cap on the attribute points, but another idea is that with the low maximum cap on attribute points, players might stock up on gear which boosts different attributes than their primaries.
