What I read was that when you take a loss you have to log off for 8 hours because it tells the algorithm that you are not a "happy" player and will seed an 'easy' game.
The way I ranked up was going on long win-streaks by carrying trash players, but at a point the skill gap between myself and the other players shrinks and I can no longer carry the team so I end up losing match after match because I am too stubborn to quit and come back later when the algorithm 'rewards' me.
I refuse to play the algorithm mini-game. Just pit me against players of similar elo and stop all the fuckery to try and keep me online to maximize my chances of buying skins.
if anything, this strategy is destructive because as more players realize the trend, they're going to get furious and quit.
