The worst games are the ones where you have 2 or more players in a team on your side. This is esp true for lower skilled games. If anything goes wrong, they start trash talking, blaming etc the outsider for everything and anything. The solo queue seems to be badly implemented - I got a level 7 player with a very small number of matches in my team, have 800+ matches for myself, he didnt even know what a chick/courier was. Played chen on lane and fed like crazy, didnt communicate either.. I play on SEA and EU West too.
