If there is a Necromancer who can build creatures like in this game, some changes there would be good:
Additional modifiers on parts. 
Right now all parts are the same. 
Agree, but your last phrase I can't understand : there're so many kind of body parts (different Head's, Torso's, Arms & Legs) ?  
 
 But maybe it's a nice suggestion for next game :
the player can put stat and/or skillpoints in his/her Creature to increase Creature's "epicness" ? 
Or a Charm or give your Creature a Ring or another item ?
