I agree with styles. but traits, no. I know people are forever grinding for the perfect traits but that's part of the game.
everybody instantly having the perfect builds they need wouldn't be good for the game I feel.
Technically they will kind of give you the ability to change armor styles with Morrowind. They will let you convert your existing armor to a new style, but it is just one (that I have heard) and just once (that I have heard).
