Yes, it is a team game. But, how does Riot justify an entire team losing LP and rewarding 5 players for something they did not earn just because someone wants to troll? Because that happened to me twice in my promo. I had to go through my promo 4x because 2 of them I had someone troll pick, feed, and then afk.
Because no matter how much it sucks when that happens, there is no way to really prevent problems like that occurring without having a real person manually look over every game...
Bottom line is, the system will always be horribly flawed, we just got to hope for improvements along the way.
Though, the new leaver detector should help out a lot. Either way though... Don't put any value into solo queue. The only reason I'm mad over it, is because the only thing I want or care about in this game is the Diamond border and I can't fkin get past Plat 2 with the current bad luck streak I'm on. I went something like 15-4 since entering Platinum tier, and in P2 alone I'm 1-7... All 7 games had my team beaten within 15 minutes and never got out of lane phase, nor did any of those matches have a single teamfight in them...
Entirely luck based man...
