The undead racial trait isnt just zombie you know... it also has the added benefit of making them immune to bleed... and besides the undead can make poison healing potions and can heal with necromancy... so its a minor inconvenience.. but the undead race add soo much that if they didnt have this slight weakness theyd be more OP than elves.
^ and they can also walk through death fog, which is HUGE to me
