Heh, I actually overshot my mark in travel form. :) It takes a try or two to get used to it, but it's definitely easier than in caster form.
I also found it easier to follow the torch shadow in the Exodar than in Darnassus. Darnassus has those trees and other things that get in the way. And SW and IF are too busy.
Other tips that help are zooming the camera view out to max distance and moving it right above your character to see the torch's shadow better.
