Cheater using kamiwyrm, and the best part of it is...

How would you know if they simply chose not to use other PvP rewards, if that’s the case?

Well for one, everyone has a vegitiger in expert, hacked it not. It’s in the eggs so all they have to do is get hacked gold and spin till they get it. And I have yet to see a singe Stratowyrm in pvp, which doesn’t surprise me because Strato isn’t very good.
