Buggy Client and Low Priority Queue
This has happened to me multiple times. The client bugs and freezes or something similar during champ select, so I exit out of League and when I start it up again, I can't get into game. This happens a couple of times and then I'm in a low priority queue and basically lose the next five games. That was the new client. So I go back to the old client and don't have too many problems, still small buggy things that everyone has seen. Well today it froze during champ select when someone else picked my champion and so I exit out of League and upon logging back in I find the game has started and two champions are on the wrong players, with the wrong runes and masteries. So I sit afk so my team can remake. I know I'll lose lp but its not that big of a deal; however, I log back in and am in a low priority queue again. So now i have to wait 20mins to lose in low priority queue.
