Legildur said:And I scoff at any build that depends on polymorph into a creature with +20 natural armor by 6th level...... obviously broken and obviously not "easy". Typically, standard creatures with that sort of natural armor are in the CR12+ bracket, and certainly have a large number of hit die. So anything introduced in a supplement that moves substantially away from that benchmark is pretty clearly a bit of joke.
Heh it's worse than that, the spell being used is the 2nd level alter self

I guess it merely add ammo for those people that want the polymorph subschool severely modified.
