Warrior aggro issues...

[Beefy]

I'm currently a level 26 warrior and I'm starting to have some threat issues in groups. My gear is solid, I have an FBSS for haste and I'm running with a Wurmslayer/Lamentation. I've heard that swapping out the wurmslayer for a faster weapon will help with threat issues. People also suggest weapons with procs like the ykeshan war club, ssoy, and sarnak warhammer, but these don't start proc'ing until 40ish. I'm getting a little tired of feeling so helpless when multiple mobs are pulled. The enchanter has one mez resisted and the mob is stuck on him like glue until one of them dies. Taunt seems to only work on blue mobs and even then it's only some of the time. Will swapping out the wurmy for another lamentation make a noticeable difference in my threat generation? Is there any other advice that would help me hold threat better? Thanks in advance for any advice given.
