So Flying is coming soon in 7.2 speeding up everything.
Also there's a thing at the Sentinax at Broken Shore which spawns demon portals, more frequently the more players kill progessively stronger enemies, which apparently drop beacons to drop even more portals/special buffs.
Some of the beacons affect tradeskills.
Sentinax Beacon of the Bloodstrike: Commands the Sentinax to fire a Bloodstrike at your current location, unearthing Blood of Sargeras.
Sentinax Beacon of Petrification: Commands the Sentinax to fire a Petrum beam at your current location, turning everything in the area to felslate.
Sentinax Beacon of Fel Growth: Commands the Sentinax to fire a Fel Seed at your current location, causing starlight roses to rapidly grow.
I really wonder how much the market will go down (varies per realm of course).
