i've been playing beta for about a week .. some people i've played with are really suspicious of knowing my shenanigans.. without even scouting they know what units to counter where my secret pylons are etc etc ... i was just hoping if there was any tool that lets you know whether the other player is cheating ..
No tool
Only if blizz do smth
The best way is to watch replays from anothers player camera. (wont work for smart cheaters tho )
