I started to think about what else might be able to stop fall damage. So I thought, what about Entangling Roots!?
So I logged on my druid, had one of my friends start jumping off the zeplin tower, and I tried to time it, so he would get rooted in mid air. Stopping fall damage.
NOTE: At this time, I was resto spec, and had Nature Swiftness. Making it much, MUCH easier.
I would click on Nature Swiftness, order my friend to jump off the zeplin tower (Or wherever you want) and at the middle of his jump would click Entangling Roots.
Stopping his fall, close from the ground, then once the effect wore off he would then fall for the next 5 feet, and taking NO fall damage.
Side Note - this will work with any other roots, if you figure out how to use them
