Last night I tanked Festergut on the 10 man version of ICC and.... I feel squishy like hell... (we downed him in 5 attempts but still...) Am I doing something terribly wrong? I chained my cooldowns the best way i could but the healers told me that I sometimes got 2 shotted Perhaps i gem too much for stamina? Any advice would be perfect! Here's a link to my armory:
Blood DKs compared to their counterparts are notorious for taking more damage, simply due to the fact that you have a self-heal built into your rotation. Getting 2 shotted is perfectly normal if Festergut is on his 3rd stack of Inhaled Blight, it was just poor RNG. CDs should be blown during this phase and if you run out of CDs, external CDs from either the offtank or any healers would be really helpful too.
Shrug, you look like the typical progression tank, min/maxing on Stamina which is perfectly fine.
If you continue to feel squishy, you should consider trying Frost Tanking. 2% Reduced damage taken and a superior cooldown (Unbreakable armor > Vampiric Blood, since it grants you armor, and parry and it's on a 1 minute cooldown as well).
2 Tanking Weapon is for more tanking stats and stamina.
2 DPS weapons is for more threat.
Frost can Tank with 2H perfectly fine. I was 2H tanking as Frost, then I got two Rimefang's Claws so I switched from my Inevitable Defeat. Now I have Burnished Quel'Serrar - Item - World of Warcraft to use with one of my Rimefang's Claws. I have had terrible luck with getting any new weapons since the patch other than those.
