Didn't see this posted anywhere when I searched. My wife was helping level on my DK and we had just reset Hellfire Ramparts when I went in and pulled a bunch of mobs and ended up dying. I rezzed as a ghoul with my unholy spec and after she finished off the mobs I just zoned out of the instance to shorten my corpse run. To my suprise when I zoned out, I was alive again and in normal form. I couldn't test this but maybe someone should try this with the gargoyle bug and see if it sticks for good.
