Creepers Arm Mid Fall

Creepers tend to start their fuse mid fall when dropping from above the player. In almost every case you cannot hear/see the creeper coming and explodes just as it hits the ground resulting in an almost inescapable blast. Ravines are the most likely areas this happens.

This is very much annoying and it would be much better if the creeper had to be standing on solid ground before it could begin arming (however not to cancel).
