I have yet to win a match. My GP is based on all of my characters, of which I have unlocked and increased most. Meanwhile, you're pitting me against whales who have spent a fortune building 8 gear 12/13 teams, thus increasing their GP to match mine. The only matches I've won were when the other player hasn't attacked and my GP was higher. This is nothing more than a money making ploy that I intend to just ignore until it's designed to be fair for all.
