Back on Cata and WOTLK, if a player were to somehow fall through the ground, they do not remain stuck for eternity, at some point they will be ported back to the nearest graveyard in or out of the zone/instances.

In MOP, you if all through the ground, you cannot get back unless you log back in, and by chance it brings you to a graveyard, however, in the case of a Death Knight starter or a Pandaren, it is as if the zone got watered down, for we can't use unstuck anymore like we did. I have a boosted Pandaren on Wandering Isle that was falling since the day I boosted him when I CoS'd a mob close to the fall.

I am not asking for them to give us an unstuck for this zone, but a way to improve falling deaths for broken zones like Pandara and Scarlet Ecslave.
This is also an issue in Pandaria zones as well, involving taxing a player.
