Well if your as clumsy as me this should help you a bit :P
i was doing the cooking daily and as i was flying back up to dalaran and i pressed a spell -.- and dismounted mid air
as i was falling i pressed metamorphosis fast and pressed demon leap as i was getting close to the ground and to my surprise i didn't die :P
this was from dala to crystalsong forest and i took 0 damage
i think this should also work with the warriors new charge thing as it also jumps in the air i don't know the name of that spell
