Low Priority Queue

Riot's client is unbelievably stupid. There are times where the queue will say "Unexpected error during ready check" or times where the "Ready check" thing pops up for less than a second and then tells you that you declined it. I'm in low priority queue times at the moment and the "Unexpected error during ready check" pops up after I accept the game. It then makes me go back and restart the 20 minute wait before getting into an actual queue. This is a basic part of the game, so why is it that Riot can't get this simple mechanic of their game right? It's insane to think that Riot can fuck us over time and time again, but because the game is addictive, people don't leave. Like what? Fix your fucking game.
