For fear kiting, Intimidation is great!
For the hot key that I used for singing the level 26 fear song (Appalling Screech), I added a /doability 4 (or whatever.. the Intimidation skill).
Sometimes screech would be resisted, but intimidation would stick, and vice versa, of course. So it made fear kiting more reliable and less likely for the mob to turn on me and do damage.
So, I'd twist haste, slow/snare, and fear, throwing in hp regen in now and then. Of course, this was before I learned how to swarm and AE kite. But still, fear kiting can be useful in some places.
