I've got a shade, it's pretty fun. Guy charges at you then POOF you vanish and he's all derp. It's kinda crap at first, but once you level the ghost precep you can walk through most a map just by following people, occasionally switching to another. Then when you're done following them a quick melee kill & off you go. ^_^
It's also good for charging at people yourself, so long as you're not being staggered from hits or attacking you'll vanish when you get close. Run into a group, vanish, give them a second to move where you want them & slaughter them all.
In other more important news - today's patch fixed those broken waypoints. \o/
