Nostalrius Begins - Quality wow vanilla realm (1.12)

I have a lvl 14 druid, and was thinking about tanking RFC. On my warrior I can see that some of his abilities have aditional threath, but Bear form and maul doesn't. At least I can't see it on their tooltips. Am I missing something?

I'm pretty sure that bear form is like defensive stance, it has a built in modifier to increase threat.
