More ways to deal with bots than removing this option for players. I like having these options so I can rush my own characters and muling(not for d2r obv).
And every time you rush a new char fill the game with mules, so that while they are in party they complete the quests aswell, get them to hell and do The Hellforge for each of them to get a rune 
I like running two accounts there’s plenty legit reasons to do so. If sandboxie doesn’t work I have a top notch laptop to run it on.
‘If you were me then I’d be you… and I’d use your body to get to the top! You can’t stop me no matter who you are!!’
Windows 10 has a built in hyper-v so you can easily load multiple virtual machines. Each virtual machine can run an instance of diablo, no need for 5 computers and you can control everything from a single computer.
And what machine you must have to run multiple d2 instances with that game system requiements ?
