I was sitting here thinking that I haven't seen anyone from Death Dealers for quite a while... until I remembered I haven't played my imp characters for a long time. Doh.
Unless I missed it when I was reading, Lorrick's second phase (40% to 10%) seems noticeably absent from the guide. It's pretty straightforward to be sure (KB/CC adds, interrupt Ravage) but I would still think it warrants a mention.
The only other thing I can think to add is that if you overgear it a decent bit, you can three-man it
