Upgrading my warriors aggro weapons?

[Varren]

Can you channel if you're corner tanking? I know that on my warrior I can corner cast, which is casting in a corner, running around, then ending up at the exact same spot before finishing casting. For some reason it doesn't always work, though...

And by the way, to the comment about flying kick/backstab producing more aggro than damage produced, so do all hits. You generate hate equal to the damage potential of each hit, regardless of whether you miss or hit for partial damage.
