I've heard of this method before and only tried it semi-recently with a new villain, just to watch for progress on the bar. My main 50 Rad/Rad has had a Carnie mission forever, and wouldn't ya know there were two (even level) Jugglers right at the door? To easily get into rest, I simply opened up with an RI (Radiation Infection) and hit rest right after that, along with putting my heal on auto.
They're currently doing 290 damage (each) every 5 seconds or so (which will also be her total badge count whenever I get the badge
). Not sure how quick this may be compared to any other methods/mob choices, but I'll take it. I don't even have Unbreakable yet.
One other thing to note: there's at least one base item that requires damage to be taken. So especially if you're in a smaller SG, consider doing this in SG mode.
