Discalimer: We are talking hypothetically here. I know that we are not using Inherrant Bonuses (IB) for this game.

The thing is that the IB does not replace magic items. The two do not stack, you just take the better bonus.

Also, Defenses and Attacks are not boosted at the same levels. for example. You get a +1 to attacks at 2nd level but the +1 to defenses does not come until 4th.

Its just another way to even out the math.
