changes to ranked system RIOT

riot the best way to change rank and to make it more fair is do what heroes of the storm does for there ranked, there ranked isnt just one map but 7 maps with diff objectives but more or less the same end game kill the nexus however if league changed ranked to randomize between diff game modes instead of just doing summoners rift i thnk that would make leagued ranked more fair. but many people will compl about this idea because it is more challenging doing ranked when you have dominion aram, summomners rift or what ever game modes you include in ranked
