As promised, I'm posting some more stuff. Here is a duo EE LoB that my guildie - Short and I did today.
The tactic used wasn't really anything out of ordinary. Short on dogs and pillars, I was kiting LoB. We killed all the trash, at the beginning, then all the pillars, then a good half an hour of kiting, DPSing, sometimes ping - ponging aggro, countering specials and healing each other in a pinch. On the last phase we killed all the trash until they stopped spawning. After that, we destroyed the pillars and it was done.
