I guess i havent played many other games with rating systems. Just starcraft. IF i recall correctly you cant play diamond players if ur in bronze? You have to move up first....
and this game is so small and complex, differnt there are so many new players new accounts, its really easy to "farm" points.
But hey if eveyrone likes having fake 1500, 1600, 1700 players, keep it as is i guess.
