fastest/most mobile class

If Corsairs get a delay that makes them faster than NLs, I hope they at least think with a brain, and make Flash jump like an attack, and I mean by that that infamous pot lag thing I keep repeating all over the place.

But yeah, prety much, Night Lords are the best moving guys out there, Night Walkers being the same but sooner.

Hmmm?
NLs have haste coupled with FJ, and most NLs I see can go faster than me if constantly FJing while I'm recoil shot+wings traveling. The pot lag makes it more difficult to keep yourself alive, but I don't see it slowing you down to below a Corsair's level at all. Even with the KMST balance patch, recoil isn't faster than FJ.
