Phantom Rune hack being used
I've encountered this a few times, but now I've got it figured out. In game the champs have extra stats, as if they had extra runes. I was playing against a Jarvan as teemo and he kept running me down, which made me curious. He had basic boots and a movement speed of 402. That's not possible, and throughout the game it kept going up, all the way to a bonus of 135 at the end of the game. His other stats were also off, which was obvious when he ended the game with 71 ap and NO AP ITEMS. I pulled up a replay and watched...and the numbers were different! No bonus movement speed, no ap at all! Somehow these guys are hacking the in game play but not the replay system. So if you go to get 'proof' in the replay it's not there.
Riot please find and fix this. These Phantom Runes are giving these guys free wins, and I'm pretty sure its not a glitch, but deliberate hacking based off the flippant attitude of the player. I flagged the cheating, but if you go to check the replay it won't show. It's only in game. I suppose you could measure the pixel movement on the screen shots and see if it matches the stated movement speed if you want proof. Because the math won't add up to what's being recorded.
The Phantom Rune hack is real. Please fix this ASAP.
