Warrior tank threat issues
Hey guys. So I consider myself a decent warrior tank but recently it seems like more and more I am losing aggro, even well into a fight. My guild is on heroics now so the dps are putting out alot more, well, dps. The classes that seem to pull the most threat are DKs, mages, and fury warriors. It's usually not too big of an issue as i'm typically quick to taunt but as far as I understand holding threat shouldn't be an issue at all. I'm frustrated because I can't figure out what i'm doing wrong. For regulars and dungeons I have a threat set of gear focused on hit and exp which helps but even then i'll lose threat occasionally. As hard as bosses are hitting on heroic however I can't really afford to drop much mitigation for hit and exp.
Here's a rundown of what I usually do for bosses. I open with taunt then heroic throw (i've always had this vague idea that any threat you do after a taunt is increased though this could be completely wrong, haha). After that i'll usually Shield Slam, HS on CD, CB, TC, Shockwave then apply debuffs such as devastate, rend, demoralizing shout etc. If I know establishing threat is an issue i'll hold off on debuffs and focus on my big threat abilities for a little while to give myself breathing room. My threat priority is then roughly CB/Shockwave>Shield Slam>Revenge>Devastate>TC>etc but not always in that order. Rage is never an issue so i'm able to spam abilities every GCD with HS inbetween at times, usually just on CD.
Even after all this i'll watch people creep up and pass me by on omen so I keep ready to taunt if they do infact pull aggro. This is usually only an issue within the first 30 sec of a fight but on occasion well into it as well.

Sorry about the long post. Any feedback at all would be great as i'm always looking to improve. Thanks again
