ShiKage's Big Bang Paladin Build

Considering CO increases skills by two, should I leave HP Max on 8 and dump the rest of the points on Iron Body?

Skip Iron Body, HP Max is glitchy if you max it with CO and you'll randomly lose 4% hp.. Even at 200 def, Iron Body is mostly useless at higher levels, it won't make a difference if it's 20 def less.
