Save money!: you can use all of your normal DPS gear, no need to avoid AS like you do in tempest rushing to increase spirit regen. In fact, the higher your AS, the more damage Submission does.
Run very, very fast!: it takes a little bit of technique, but in my experience I feel it's faster than I can Tempest Rush (I couldn't get enough DPS with the special gear requirements and I would have to circle back to kill things off, slowing down my runs)
BUDDIES!!: Air ally running around with you makes it feel like an AoE party of awesomeness!
Things die without you touching them!: the radius on Submission and Firestorm is nuts. You can care much less about where you are running than you do while tempest rushing.

Feel free to add whatever you see fit. I'm currently using Air Ally to increase AoE and Blazing Wrath for a straight DPS boost, and Chant of Resonance so that I can spam WotFS more often.
The build centers around increasing the damage of Submission (your primary damage dealer) with AS. I think Firestorm is the right choice because you really aren't punching enough to make cyclones and increased radius is the correct choice over Bladestorm because MATH! (some equation involving the area of a circle). The technique is to jump around the map with WotFS, using it especially on the last mob in a pack so that you can run between packs more quickly.
