we'd need to be able to attack up to 3 kicks per round or have some feet with insane DMG+ on them.
Actually just need to increase the speed. I was fooling around with imps because that's the trial my Ursines are on. I'm doing about 800-900 per combat round when I hit twice, which is awesome, it's like a mini weaponskill every swing, but the swings are sooooooo long that it doesn't matter.
Also, the fact that you have to use either Dragon Kick or Tornado Kick just craps on your damage.
Anyway, it's a slippery slope. Ideally it would be nice if Footwork was at least viable for NMs with really nasty spike damage, like Turul, but even then who honestly bothers to bust out Footwork?
