I set up at imps when possible, but I also monitor it while I'm watching TV and working on other stuff on my other monitors. I would absolutely recommend against AFK botting here (like going to bed while your bots are killing). Not to mention, it's a dungeon. Even with MQ2Navigation you're going to have idle time waiting on respawns if you're not manually pulling into the Stone Spider room or main Imp platform. It is very easy to stick out here when botting.
I've gotten 4 cloaks so far, but last couple days been dry.
