Most people don't know this, but I positively HATE FARMERS because it is impossible to gain any trophies or resources while being farmed! That is why I'm glad Supercell is adding this to the game!
Coming soon!!! Leagues: compete in your own division!
✔ Joining a League is easy: just own 400 trophies or more!
✔ Get a Loot Bonus out of every victory just from being in a League!
✔ Loot Bonus increases the higher you climb in the Leagues! - 14/04/2013 
This is a reason to gain trophies! I will probably be faceing more people bent on gaining a balance of resources and trophies than normal now, but oh well.
