Okay so I was thinking if different pets gave different extra stats like all dragon type pets give 5+ dmg and 2%+ hit and balloon type pets would give 2+ of each regen and 2+ dmg and all other types of pets (minotaurs, ducks, turkeys, and whatever else) gives 3+ armor and 2+ crit.
[something like that]

I think this would be very cool and up the strategy in all PvP.

Just some thoughts
