Because if you are Frost then HB SHOULD be your main AoE threat generator. I pull using DG, DnD, wait on mobs, HB, BB to finish. I would say at least 50% of the time I either have a KM proc left over from last pull or get a proc while waiting on mobs to come to me after the DG. HB Crit is really nice threat generation. Not to mention the whole Frost Fever and Icy Talons proc for my group. I can pull without DnD and often do and never lose aggro. It is the same principle. I use HB to produce AoE threat. DG, wait, HB, BB, BB, Oblit. (and hopefully Rime & KM proc for a free crit HB).Originally Posted by Pope
Maintaining aggro in Heroics is not hard for a Frost DK. DnD is ok, but you should check the TPS it puts out. HB (especially if it is glyphed and adds Frost Fever to everything) will put out way more TPS. Not to mention reducing your incoming damage to make up for not having Block. It is a much simpler rotation than using Pestilence. Almost as easy to tank as a Pally. Almost....
