So, I got stuck running Haderax for a while yesterday. There's a trick with Maya and her Recompense skill that allows Haderax to kill himself instantly when he enters the area. I pulled a bunch of legendaries from him - multiple Volcanoes and Nukems, a Conference Call, Hammer Buster, Lyuda, Flakker, Slagga, and probably some others I'm forgetting.
I decided to push through the main story a bit, to get some levels in. I really want to hit 80 before BL3 gets released, and possibly start another character but we'll see!
