Im not sure if I agree, SE just isnt aggresive enough, I played WoW for 3 years and only came across bots twice, one was a person in my guild and another was a random.
WoW also uses Warden just like Overwatch does.
The detection for Warden also relies on virtual inputs and it makes things very hard for the coders as they have to do a lot more coding and bug testing.
Having read a popular cheat forum the attitude towards FFXIV and WoW/Overwatch is a lot different, they fear Blizzard but feel very safe with FFXIV which confirmed my observation from my Anti-Virus about there being only server side checks.
