Having two teams in the same league is defenitly against any fair play. But if your worried about the poss. bonus, you can watch some random games and invite everybody whos assisting these matches to your friendlist. It's same as with gifts. You watch my match, I watch yours. I If you do this for some time some of the people you invited will cheer for you when online and give you the bonus. Having a lot of friends gives you a lot of fans!! But in my opinion it won't make your team play any better or win more matches.
