Just my guess:Wulf Ratbane said:Somebody explain the need for the +1/2 level AC bonus to me.
It is a fundamental part of "the math works at every level".
If BAB is already known at a given level and the potential modifications to BAB and AC are known at a given level because magic items now have levels, then giving AC an advancement by levels would allow the system to micromanage the chance of a hit being the same at 14th level as it is at 3rd level and at 29th level. Obviously feats and such would need to be built in as well, but that could be controlled if the goal was to do so.
