Actually my wow is taking more like 800megs. Not sure but I cant see how PQR would be taking that much. Cannot load bites that doesnt exists so it does not make sense. You mean PQR is taking 800megs!? Pic or it didnt happen!
Regarding PQR vs HB banrate, HB bans come most of time from LCP detection and other players reports. That mean repetitive pathing. If we let a bot with a short profile go for hours, server side algorythm will see the most used path and if it doesnt look human it's flagged an investigated.
I'm not sure if PQR is warden safe. HB is looking for warden and if it starts HB should hide. I think both have totally different uses and are safe as long as the user is using it right. Been using HB for more than 2 years personally and I love it. Never been banned/susp ever. I have a bot account that runs over 60h/week unattended(it's on a computer in a wardrobe and I VNC it from my main PC) and my guild and I never farm pots or feast. The bot is doing it for us.
HB is safe. Using HB is tricky.
