As JPhack said:
If you queue, you are a subject of the MM System, and the MM only wishes you one thing: For you to fail miserably if you fly well, or to help you win by being carried by other good pilots.
So basically, the ones that are bad, are used as handicap to destroy the hopes of good players while the bad ones see as their saviors the ones with high skill.
Basically, MM is the system created by satan to caretake us. No matter the tier, no mater the ship, no mater the skill, the MM will try to put you into bad spot, having a wipe or not. If a wipe is done, all i could imagine is veterans farming the badies so hard that half of them quit the game ( asuming all veterans stay on the game after the wipe).
Sumarizing (dont know if this word exists, im very sleepy for some unknown reason): If someone is badie, it will fail no mater what. 1 month ago, i was doing some T2 here and there, using some R6’s, and we could sometimes find R9’s on the enemy side, and many of those times those in R9’s still lost the game, why? Cause they are badies, so, no wipe in the world will fix that, unless you wipe all good players from the face of the earth.
But this is the thing, you make the assumption that all bad players leave games.
If bad players left games… then why are there people in World of Tanks with winrates of 45%, who assumably get creamed every game, still playing said game?
Being bad at something doesn’t necessarily force you out the door straight away. Having to wait 5 minutes for a match however, is more of a deciding factor. You spend 5 minutes waiting for a matchup… then you play for about the same length of time. It’s like sitting in a theatre for an hour, to watch an hour long movie… and the MM’er wait times add up and cause much more frustration than any amount of getting screwed over will.
