I'm curious, how many bots do you run, or just the one? Have you had a death yet on other bots? 24/7? What paragon have you reached and how long have you been running? What's your gph, xp per hour, and legends per hour?
Basically, it's just not worth it, but you're welcome to try for yourself. I've killed off a ton of toons playing HC manually, and a bot is going to be worse than a human. If you bot HC, expect to lose them to something eventually. It's like botting in general: getting banned will happen...
Pretty low gph rate, doesn't seem worth it for the risk you put your 500M monk at. Hope you're getting good loot drops to make up for the lack of gold. At a guess, are you botting mostly just to get your paragon level up?
