I know that there are ways to get to Elwynn Falls that involve falling underground, slow falling, and then swimming underground up to the Falls. I think this method may have been found or maybe it hasn't, but I couldn't find a video of it so I thought I might as well post it. One good thing about this way is that you don't need some 30 seconds of slow falling, Noggenfogger Elixirs work fine.
