So lately I've decided to pickup tanking on the side and I've been trying to chose between these two specs as they seem to be the 2 most popular ones among tanks. Right now I am running the unholy version and it has amazing AE threat. Mix this with the AN trinket and the DND glyph and you are an AE tanking machine!
Any thoughts from the pros? I'm sure people have talked about this before... Didn't find any threads on this as of late though. Seems like most people are going with frost but unholy just seems too good right now.
Managed to tank Heroic AK last night as 5/11/55 without wiping once and I'm not even def capped (close though, like 530 def), i think BS is a REALLY nice addition to the cooldown rotation and AMZ definitely helps with caster pulls.
