Questions about Main Tanking 25 man Ulduar as a DK
So I have been off tanking for my guild ever since I hit 80 back in the day. I love off tanking but I'm not to fond of main tanking. Due to 1 of our warrior tanks not having time to raid anymore and the other switching mains to his hunter, I now find myself MTing in Ulduar 25.
I seem to have trouble holding aggro. I'm constantly in a race to stay ahead of mages and warlocks. If they dont use their threat dumps they will pull aggro. I need constant misdirects and tricks put up on me.
I use a 12/51/8 Frost spec.
my rotation goes: IT > PS > BS > BS > OB > FS and then usually repeat.
My question would be, do you have Rune Striked correctly macroed into all your spells. It should read /cast !Rune Strike. If you don't have the exclamation mark your turning it off as much as your turning it on. If you don't macro it at all, your missing lots of threat right there. Glyph of Rune Strike macro will also get you more threat mileage than Death and Decay.
I found myself in a similar position when 3.1 arrived. Mostly off-tank so I wasn't too worried about threat (was unholy at the time), yet when I was needed to main-tank, the threat wasn't cutting it. As keeprock suggested, macroing everything to Rune Strike helped a great deal, and I also went to blood spec around the same time. Myself and a few guildies noticed a nice threat increase with blood.
