Uldum and Vale of Eternal Blossoms skies are not safe anymore!
The deal is: gigantic air worms ‘from Beyond’ will crawl out of void breaches from Ny’alotha and slowly float around the zones. From time to time. If you happen to be close to them, you’ll get a nasty movement debuff and a breach into your health pool. If you try to contact them, they eat you alive.
Plan of action: don’t be AFK in the air, you’ll be fine.
I think it’s a fun design. Basically it’s airborne Fel Reavers which add up the excitement and keep you on alert. And they are really in the vein of patch lore.
And one thing to say for those who’ll be whining: “Blizzard wants to take the skies away from us, one way or another!”. Uhm… when was the last time you tried questing in western Dragonblight in Northrend? Fly into the snowy woods with an alt of ~60-80 and tell me how soon you’ll be pecked down to the ground. It’s not new, not even close, and air threats are there ever since flights themselves were introduced.
What I see in these worms now is a nice pinch of flavor to the ongoing events. Bring them on!
