Which sort of talent build is best to do for an instance boosting DK? I probably won't play mine much beyond boosting low levels at this point. I see a few talents in the unholy tree (Desecration, Wandering Plague, Corpse Explosion) that could be useful there. Then I see you mention Howling Blast and looked into that tree. The 8-second cooldown on it sounds powerful against mass mobs, and it can be modified with several other talents in the frost tree. So, does anyone have a sample build I can peruse?
