A huge disparity between players that play for fun, and those that don't

So lately I've been seeing in my matches that there are a huge disparity between players that are playing just for fun, and other players that play for real and have fun when they play against challenging opponents in correlation with teammates that also try hard.

I really want to push for ranked games to decay points AND ranks for those who are not active in them to alleviate this disparity between players. You cannot have balanced matchmaking with a pool of players that don't play enough to achieve active stats.

Player 1 Here is an example of a player that plays for fun, he will queue up arams on his spare time and hop onto a ranked match probably once every two weeks just to see what it's like. This is where we see players that go through placements, land gold and above, and are content with a game here and there. This is already leaving Player 1, his teammates and the enemy team with a scenario that is doomed for failure, toxicity and overall a bad gaming experience.

Sure I understand that playing blind pick, arams and flex queue with the buddies is FUN, but when ranks aren't decaying and players are "away" from the try-hard scene this tends to leave teammates with a bad taste in their mouth when they lose. With the only option left is complaining and toxicity.

Player 2 Here is a player that plays STRICTLY ranked, as I explained earlier this player is playing to seek a challenge and have fun from displaying how good he is at the game. This player will usually "try" to correct Player 1, but turns out that Player 1 already knows the situation and takes offense to it.

Most cases Player 1 will legitimately play to lose, just to provoke Player 2 and everyone else that is against him, goes straight to all chat and goes, "Report Player 2, toxic' over a simple comment as "Hey Player 1, play safe or under tower.. you're feeding".

So what can be done about the two different playstyles in league of legends to prevent this? My proposed idea was to simply increase how quick players decay in ranked, because right now the fewer games players have.. the more frustration there will be.

I have 210W 208L in solo queue ranked, and even now I feel like I should have more games played. And it's urking when I play a different role, there will always be Player 1 with 40W / 40L that really shouldn't be here.
