Improving Ranked Queues - A Possible Solution That Lets Riot Keep Their Changes
There is only one way I can see them keeping this new system in while still having it functioning to the satisfaction of MOST people: make MMR a measure of individual player performance, instead of a measure of wins/losses. Currently, MMR means little more than "here are the points I got for being in games where my team happened to win". Notice the problem in there? "Me" doesn't even factor in. My own performance means nothing.
What if, instead, MMR reflected how well a player performs in games? What if MMR counted things like how well you warded, how good your KDA was, how well you farmed, how well you contributed to the securing of objectives? Sounds like it'd be complicated, right? Well, Riot already has most of that system in place just for shits and giggles, and that's the "Champion Mastery" score system. If MMR tracked something similar, then this new matchmaking system would be just fine.
Here's what I mean. Let's say that you have a good game early on in Season 6, and you did what YOU were supposed to do in your lane, but your team was just pissing around. With this new MMR system, even if you lose the game, you would gain/lose MMR based solely on your own personal performance. You could lose games and still go up in rank, because YOU still played well! Wouldn't that address everyone's concerns? This will take the focus in League of Legends off of just happening to be in games where your teams win, and put it squarely on encouraging greater player performance, regardless of how your team queue is set up. This would also encourage all players to encourage each OTHER during games, because encouragement leads to better overall performance. The positive encouragement would also mean that players are motivated to improve and get better.
If this all goes in unchanged, the new ranking system will drive away most of League's players who play the game for a tough and competitive experience. If we put in performance-based MMR, all those problems go away.
