Today during a BRD run, we were clearing the Grim Guzzler. I, as a Healing Druid, have pretty little to do, so I ran around, throwing Rejuvenations on people, when suddenly I saw a under-the-floor view of the BRD Map. I was like, wow, my cam slipped through the wall (like it does when you Chain-Eagle Eye to below Orgrimmar). But then I noticed I somehow was...well...invisible. I suppose I stepped through a piece of the wall where they had badly painted collision, e.g. where you could step a bit towards (and thus, into) the wall, than you should be able to. Strange enough, my shadow was still visible.
Screenies:
1.: Stand here:
2.: Take a step towards the wall and poof! Invisible! (You may notice my shadow against the wall):
3.: A close view of my lonely shadow:
Well, that's it, maybe someone comes up with a cool idea for exploiting this, maybe it's just funny. Still, I'm glad to contribute.
