Threat Problem

[Khrosis]

I am having problems with threat generation, not against DPS but against other tanks. My main problem being Paladin tanks, ones under geared and less experienced are either pulling off me or biting my ass the whole fight. Basically I just need an opinion from other DK tanks on whether or not they face the same problems as I am....or if im just being stupid and doing something wrong.

My basic rotation is:
Single Target: IT>PS>BS>BS>OB>OB - Rune Dump
Multi Target: DnD>IT>PS>Pest>HB>BB -Rune Dump

Heres my armory:
The World of Warcraft Armory (http://www.wowarmory.com/character-sheet.xml?r=Moon+Guard&n=Khrosis)

Feedback would be welcome.

Protadins have really good threat generation so dont be to worried about them pulling threat off of you. If anything its theyre fault and they should be watching their threat if they're supposed to be OTing.

For any rotation you want to trigger Blade Barrier asap, try opening with D&D - IT - BS - PS - OB/FS etc.
