Monsters already double dip on their offense, because they get more accurate and deal more damage. HP inflation means that high-level characters can soak the extra damage, but that still means they end up getting hit more. If PCs also increased their AC, in addition to HP, then that would just bring it to parity.Interesting idea. The problem I see, however, is that it seems to "double dip" the durability/skill of higher and higher level PC's.
Of course, given that high-level characters are still way tougher than they should be, it seems like HP inflation was "balanced" around countering both increased accuracy and increased damage. Monsters get a little more accurate, and deal a bit more damage, but characters have waaay more HP.
