do people running only CR's get banned during Bliz's ban waves? Are there alot of people out there running CR only that survive ban waves?
If banwave happen due to detection of Honorbuddy, it do not matter which product you are using, you will get ban anyway, if happen to bot in period of time when detection was pushed.
Tho, currently i can call Honorbuddy safe enough - we haven't got any banwave since 1st of February 2017, which is quite good.
But also it can happen in any moment in future. So recommendation - do not bot (do not use any bot or automation software, not only Honorbuddy) on wow account you afraid to loose. Or be prepare to be banned in some day in future.
Botting in whole is not safe, no matter which bot do you use or if authors of such calling it 100% safe - it's a lie. Any automation is forbidden by Blizzard and you can get ban because of it.
So, not one can grantee you 100% safety.
The only different of CR from auto-movement products - if you use CR with manual movement it's impossible to detect it by Players, as it can't stuck somewhere in open world.
But still, it won't save you from ban caused by platform detection itself.
