"Addressing your concerns for the 2019 ranked season" = "We're ignoring the fact you dont want it"
Just dont change it. I have literally not seen a single person say anything positive about this. It has more flaws than the current system (which is already shitty) it's over complicated, not needed, and just all around dumb as hell.
Some points to "Address our concerns" almost make it worse such as:
"Let’s say you’re the same player and your duo hits you up. They play top and suggest you queue up for each other’s positions and trade so you can get easier games. It takes a game or two for us to see a pattern of trades, but for those games we’ll detect that you traded positions and adjust accordingly—you’ll have decreased LP gains and increased losses since your team was favored to win. After that, the link between your MMRs will tighten and you’ll get matched in Gold games regardless of the position you’re playing."
- This shit literally doesn't even exist in this system, the new system you're making is just adding problems, and its dumb as hell.
"(How long it'll take to rank up in the new system) ... We can address this concern using several mechanics we’ve already built into Ranked. We want players to be able to climb to their peak skill in two or three positions without playing significantly more games. True fill players will have to play more games if they want to max out their rank in every position, but nowhere near five times as many"
- This doesn't even make any sense, the grind to get an overall good rank is fun, that's where the ranked enjoyment is. We want to climb to our "peak skill" overall, not in just a couple positions. Regardless of if it wont take as much time as we think, it'll still take a lot more time.
"Imagine you’re a Gold mid main. If you decide to go play a new position like top, matchmaking will look at your MMR in mid and other positions to estimate your initial skill. That means instead of getting put into a Bronze game, you’ll likely play a Silver game."
- So if im a Gold ADC, and i go do mid lane in normals for a month, ill go against people who are worse than me, in a role i know well? Good shit Riot.
"We’re adding a mechanic called splashing, which reinforces how every game reflects your skill while preventing abusers from ruining off-position games. It works like it sounds: At the end of each game, you’ll splash some LP to your other positions based on your normal gains and losses for the position being splashed to"
- This is literally just a worse system than we have now. If i main ADC and i get filled to Top then we win somehow, i get LP for a role i dont play and as high as 6LP for my main role? So instead of getting 20+ LP for the win, i really only get 6LP that i care about.
"We believe positional matchmaking and ranks can give you fairer games and meaningful ways to challenge yourself. At the same time, we heard an important piece of feedback from you that we agree with: Win or lose, every game reflects your skill and needs to matter regardless of the position or champion you’re playing"
- No one care about positional matchmaking, we want to be able to pick our roles, play them and have an overall rank. The second part of this point, is saying that you're going to keep the system we have now, but make it worse and more complicated.
As i said, i have literally not heard a single good thing about this ranked change. It over complicates shit, its unwanted and definitely not needed. I would respect this change if it made ranked like team builder, if you could NEVER get autofilled and you could only select one role at a time, then this shit makes sense. But overall there's too much going on to make this be a good change, i literally couldn't imagine a worse change for ranked. Also, what the hell is up with Riot constantly making HUGE changes that no one wants? You dont need to reinvent the game every 6 months. This game gets further and further away from the game i fell in love with every time there's a major update. People complained about the ranked system, but this is just making every possible thing worse.
Please Riot, for the love of god PLEASE listen to the community and do something smart - scrap this shit idea and let it die.
