So basically this is a "Morph" now and no more Summon ?
Do you have a "Pet Shade" then ? that you must try to keep in safety and in view for casting spells on you ?
I didn't played a lot this kind of class which remove most of basics controls to fall down to "horrible" Pet Controls Only...
Anyway using DOL for this would change a lot of rules around Pet/Player Damage and Hit Rate calculation (which would fix a lot of this class weird stats tranfer from summoner) probably requiring some balancing !
