It won't.
Unfortunately we ran into this elevator bug (and I am convinced it is every single elevator in the world ATM --my alt has seen them bug on the elevators in Searing Gorge), in the Mechanar, twice about 3-4 weeks ago.
In the second group, the last boss Pathaleon was literally *flying* from the top floor to the bottom floor, making us disconnect and having some of our members "fly" as well. Needless to say we could not finish our heroic daily.
They just get stuck on evade mode and you cannot level the weapon skill.
While it is kind of funny to do ..I don't really recommend it. On my server ATM, there have been bugged mobs for days.
The kids who have their hearth set to their opposite alliance in Shat (if you're Scryer but your hearth is Aldor, etc) they've been getting a kick out of this trick :P.
I've gotten the guards to "fly", as it were.
Here's an SS of a flying guard in Shatt:

Bad shot and bad angle, but you get the picture :P
Enjoy! And also +rep!
