I'd suggest you glyph up your eye of kilrogg, to make sure it doesn't get killed instantly on this.
Now, what you need to do is use your eye of kilrogg, run it into the mobs and then QUICKLY run into the guards. If you do it right, you'll manage to aggro the mobs and the guards'll start attacking them. Throw up a DoT or two and voila, you'll get your 60 rep within moments.
( I don't think this is a repost. )
EDIT: Probably doable as a hunter with eyes of the beast, too.
