I would prefer dragoon without pet, but if they can they could make it something that you can decide, example

You are soloing so you call your wyvern, become a bit weaker and fight with it to help you kill the mob, you are in a party and want to do as much damage as possible then you absorb your wyvern and become stronger, but if they dont want to add an option like that they can just forget about the wyvern and make dragoon OP.
