Do you have a follow the leader button? This is usually what I use when a fearing person is trying to gank me. I'll lay down my tremors, they'll aoe fear, tremor cleanses. So at this point hit your follow button, then press some stopfollow button (either universal movement control, or anything really). At this point everything will be facing your usually follow target, and if that's your tank character, you're ready to continue dps.
