I have noticed lately that my threat has topped out at around 6K tps. I have a 5400 gear score, and am successfully co-tanking ICC-10 through Saurfang. The guild I am in is a casual raiding guild so we work slower than most.
On Tuesday Patchwerk was the weekly. The guild gathers 16 people to run the weekly. The pull begins with a DK and two pally tanks. The DK opens up at around 8-9k tps, no hunters or rogues in the group, so that is his threat. I am running 5-6k tps and the other pally 4-5k tps. During Heroism, DK hits about 13k tps and I settle in around 7k tps. The DK outgears me, and has a gear score of 5600 I think.
I know the 9-6-9 rotation and use AS every time it is off cooldown. I use SoR after Judging vengeance. We always have a Dranei in the group so that helps me make hit cap.
I am looking for advice or answers.
