Occulus Extra-Life (sorta)
This works best for the last boss.
As most of you may know, when your dragon gets killed you are dismounted (duh) after this you usually die from his aoe attack when he does it.
By jumping to the 'ground' after you get dismounted you get zoned out and appear with your body(not ghost) right outside the instance entrance. You can quickly zone in and mount up(u have to spam your mount cause you get in combat pretty soon after zoning in) and go grab your replacement drake.
This works best when you are not the main tank or main healer cause the group will probably wipe by the time you get back
