This has to be bad joke


So I soloQ and I get matched with 4 russians, noone of them speaks english but hey thats normal. But if 2 of my teammates leave the game I find it hardly fair to lose elo since I cant win game on 2200+ elo alone.
Why I should lose elo in game which we would win if I had two teammates, but instead I get two bots which dont even listen to commands. This is retarded joke, Im getting punished for something which is not my fault. I cant change if my teammates leave or not. If I atleast lost lower elo but I lose -25 elo in match which was clearly unfair. This is why I dont wanna buy premium account, since this happens every 5th match.
