Because you are a fckin idiot that's why, because you get 20 lp when you win and you lose 15 in a loss that's why, because your pathetic 50% win ratio is enough to make you clinb devisions that's why. Because when i win i make 8-9 lp with an extreme of +6 the other day, and when k lose i lose 19-24 with an extreme of -26 for one fckin loss!!!! Because my impressive 60 % win ration isn't enough to get me out of bronze 4 but fags like you can advance through leagues with 50% so yes people complain and for a good reason.
Because MMR sucks and riot won't do anything about it.
Maybe you are blind, maybe you have no idia of what elo hell means certainly not complaing about trolls, feeders , afks, i only complain about fckin lp gains and losses who don't reset at the beginning of a new season.
Does ell hell make sense to you now?
