So I've always been one for trying random things in the game to see how they work. So I came across the huge put beneath Elegon and thought hmm huge hole + no death from fall dmg glyph = ??? Something interesting
Not sure if it changed, they probably did, but on beta there was just a normal (invisible) floor in that hole, and Pandaren of all classes and Rogues too I think would survive the fall and be stuck there. Saw many a stream with people HS'ing out of there xD
