Season of Discovery has made a habit of changing up old content to make it feel fresh. It started with the Level-Up Raid version of Blackfathom Deeps, then instanced World Bosses, and reached its pinnacle with an outdoor area being converted into a Dungeon in Demon Fall Canyon.
Crystal Vale Overview & Loot Guide — Season of Discovery Phase 5 gives us a combination of the World Boss treatment and fresh content.
The Crystal Vale Raid gives us a World Boss version of Prince Thunderaan — a Boss that was previously only relevant for people on the quest to earn Thunderfury, Blessed Blade of the Windseeker.

There is now a reason for all players to seek out the portal in northwestern Silithus to challenge the Prince of Air — and some items have piqued some interest.
