I've been tanking 10man Heroic ToC on my DK and I have been having terrible threat problems on tanking Anub'arak. Given I'm an offspec tank so my gear is not the best it could be, I'm doing the normal Blood DK dps rotation with as many rune strikes as I can get in.
IT > PS > DS > HSx2, DS > HSx4. repeat. with Rune stirkes and Death Coils thrown in.
I'm tanking against a boomkin, warlock, warrior, and mage all with about or over 5000 gear score and threat becomes a terrible problem even with using hysteria on myself.
Does anyone have any tips about the H 10m ToC Anub'arak fight, or any dk tanking tips at all.
