Why don't people test their internet connection before they enter a Ranked game?
If I could get a dollar for every time I played with an ally who had a ping of 1000, I would be rich as hell now.
I don't believe this internet problems all suddenly start once you get into the game. Most of them must have had issues before entering the game.
So many LP have I lost because people play with a huge ping and they aren't afraid to spam it the entire game.
