Is Polymorph really a 'magical' skill? It is more something about changing your physical appearance so it will increase mainly your close combat abilities? Hard to tell at the moment.
Also Summoner and Polymorph got voted that way, so the playerbase decided.
Sure, more strength classes would be nice, but honestly I don't care so far, I enjoy using hybrids anyway. In D:OS1 I had a rogue with strength and int and not purely on dexterity and he was still awesome.
