Frost DK tanking threat issues
I've been wanting to tank as Frost to get some change from my current Blood focused spec, but when I tried I had issues with AoE, I even had the talent Rime to improve my Howling Blast usage, but I was still having issues.
I used two tanking weapons with relatively quick attack speed (around 1.60 I believe on both), I've got Rune Strike macroed into all of my abilities so it's used everytime possible. I had around 160 or so hit rating and 12 expertise (not sure of the rating) when I tried.
I want to know what I'm doing wrong, keep in mind that AoE is what I've got problems with, not as much single target.
This is the Frost spec I was originally using: Wowhead - Frost spec
This is my armory: Armory - Zarnia - Scarshield Legion
(Note that my gear has improved a bit since, especially on the hit rating department)
