no, fire and earth are stronger, when a earth or fire player 5 levels under you can beat you, you know theres a balance issue, and ive tried a lot of different formations, even lightning has trouble against these two. and the only way other mains can get stronger is by paying into the game a few hundred dollars every week. if nobody paid any money, then it would become painfully obvious that fire and earth are overpowered to the point its not even worth it to be anyone else.
