And Vanguard is already being bypassed by using external tools. IIRC I saw a video about it where the cheater had the hack running on a completely separate computer.
The number would be higher too, I doubt I was the only one who stopped playing months ago when Vanguard was supposedly going to be implemented imminently.
Fun fact: you could get an account locked in under an hour if you used a command line to close the league client. Not powershell - just good ol cmd. No reports needed. Reproduced it 4 times in 2 days... Lots of fun emails with initially the support teams and then the devs. Apparently "taskkill" is the most nefarious cheat known to the gaming industry.
A grade schooler with a "learn programming in 24 hours" book could probably produce better cheat detection.
