Dungeons are pretty much ruled out because of the risk and the frequency of caster mobs. You really can't charm-exp effectively with casters, it negates the entire purpose of charming one mob to kill the other and then breaking charm to get a second kill with one or two nukes. It's also a much bigger hassle because you will get attacked now and then, and instead of getting hit once or twice, you get nuked and dotted and shit.
I'm in Lake Rathe right now, but it's not optimal. You really need at least four mobs of the same type in close proximity. The three-mob spawn is kinda useless because once you've killed the first two you're left with one mob and nothing to charm. They're also too close to split with lull and there's a red goblin walking around right next to the spawn. I've actually been doing two seperate 2-spawn towers, sailing back and forth between them in a little boat while medding.
