Broken Champions, and an unplayable game

Riot almost every champion in the game is really strong, besides a few, and if you pick one of those few champions your team will lose. For example i just played a game as Annie we won every engage, but things like Morgan 2v1 our ADC and i (Morgan was the support) to a full tank Ammumu one hitting me with his ultimate, and Miss Fortune one hitting me with her Double up. I ask and i know that many others will ask to to nerf a lot of the items in season six, and especially the masteries, and even a decent amount of champions. I have not been wanting to play the game because it is continuously unfun to play with season six having really strong masteries, Items, and champions. Saying that I have spent over 250$ on this game to purchase champions and skins I just ask if you could please Make things not as strong for it is fun again to play.
