Since 3 days I've been experiencing lags, I was just in a game with Graves(We were winning, losing, doesn't matter.) and when I went to shoot the SInged of the enemy team out of nowhere popped up 4 enemy champions and I got one-shotted. They didn't flash because we had vision, neither did they use Ryze's ult, it was just lag that was caused by the game or something. I have perfect internet connection going well over 500 Mbps, in game I play with 30 ping and yet there's these 1 second delays for no reason. I don't really care, but I lose my promo because of that and I just feel like I wasted well over 40 minutes just to lag once and lose the whole game.
