Seems interesting. I think it doesn't affect that much our attributes.
As for the skills even that staff focus is going to lose 40% armor bonus from staff power the other bonuses moved to it might make it even more viable choice. Specially losing 50% bonus from item amp on weapons makes it more interesting to use more armor pieces instead of 2 weapons.
Sure the feedback skill gives another viable option, but I'd see it more as an option for wandslingers.
