In all my years of PvP I've NEVER seen my opponent just sitting there swatting at flys while I'm able to jus pound them into the ground. Not once. "Swat at the air all you want."
I play a bit of 2v2s and almost 1 in 10 matches has atleast one person invis like this. Could be my team or theirs but its happened for years
Well at least it's not a hack then. Perhaps it's time for a PvP REvamp though? Or at least touch up on it so stuff like this won't happen?
Good news: It's not a hack. Bad news: It is a bug that has been in the game for YEARS and reported multiple times. . It happens in PVE as well. It happens in scrims as well as ques. Neither is safe. I first reported the bug via this video in a thread in the Arkham Section (Bug Section) in May 2015. Me and some fellow league mates were practicing Legends one night when it occurred. Also worth noting for the PC players that think it only started happening after the merge this video shows otherwise as the PC/PS merge did not occur until January 2016:
