Pets evolution

I think the pet's angel and devil should be able to evolve into a class and gives us a little boost that can help us a little. And we can be our pets and do a minigame to evolve them. They will also gain exp by watching us battle. The pets will also gain levels by the exp they gain from watching us batle but the exp they gain from watching us will only be 1/3 of our exp. Angels and devils should maybe have classes too like us. Ill put up a example just to show:
Evil Knight-Devil evolution
Boost-Gives Dark Powers(explain in elements) and gives a attack boost of 5(level)

Pets will be able to battle with you,
I could make them "Evolve" through a quest or something though ^^

Oh yea i was meaning to ask you, is this game going mmo?

It might do, but not for a long long time

Oh well but what will pets evolve into?

Bigger and better ones? :p

Yea but if their too big they might disobey us and leave, maybe u can give them pet armors and stuff and evolutions like our job advancements.
