The World Tree's Lake

Essentially I was exploring the Hyjal map from vanilla and noticed that the lake underneath the world tree was slightly different.

There is a chasm that goes on for a very long time (exactly the length of your breath bar).

At the bottom is a air pocket that refills your breath.

This suggests that Blizzard had planned out quests for the area and (maybe?) implemented them before they abandoned the zone. It just reminds me of the Druid quests for swim form, swimming under Moonglade and along the reefs of Westfall as an Alliance character.

Might be a repost, but I've never seen it before personally.
