Ranked system needs changes
I believe RIOT created a genius system to grade players. This system is genius because it grades you based upon all variables of gameplay including gold, CS, deaths, kills, assists, and etc. This system is the true way of telling the difference between good players and bad players.
With all of this being said, why not use the same system for Ranked LP and promotion/demotion? Myself, along with many other players, get S rank almost every game, and yet, we are stuck in lower Tiers like Bronze and Silver. Nothing is more aggravating than earning S rank and losing a game, thus being demoted or losing LP. Players who earn S rank frequently should be rewarded in the Ranked system, not punished.
I beg of you RIOT, please consider making changes to the Ranked LP and promotion/demotion system. I'm sure improvements can be made and I sincerely hope you consider it. Other than that, I truly love League of Legends and consider it to be a phenomenal, well-developed game. Thank you for your time.
