IF AMERICA CAN GO TO THE MOON WHY COULDN'T THE USSR?
Different fucking playing fields.
Different fucking games.
League's also a far more dynamic game than Dota. Constant changes to shift the game here and there, items constantly changing, new champs constantly being released, AND a vibrant competitive scene that's gotta be dealt with. I think Riot's doing an excellent job on balancing the game as they go, but eh, if some random guy thinks he can do better than people who sit around all day and balance the game, more power to him.
