Wouldnt it be great to allow pets to cast spells and put the school element pets on the gold stores and get rid of crowns and put all the stuff in the gold shops instead of crowns.
PS: And have henchman that follow and level up with you? :D
1. Pets can cast spells, train yours to get May-Cast abilities. 2. That would defeat the purpose of school only pets, and spells in Orthrus' case. 3. Crowns are a major income for KI, without that, the game would be shut down. 4. Same as number 3. 5 (Your P.S). That would make questing too easy.
