You can Build Ships in the Next World of Warcraft: Warlords of Draenor Update
World of Warcraft: Warlords of Draenor patch 6.2 will be bringing some new cool features for the Garrison alongside the usual new boss encounters and raids. One of them is the ability to build a shipyard, once you’re Garrison is at level 3. You’ll also be able to build ships using it, and then sail on missions with your trusty boat.
Hellfire Citadel will be the newest raid introduced in the game, featuring bosses including Kilrogg Deadeye, Gorefiend, a reanimated Mannoroth, and Archimonde. A new Mythic difficulty will also be added to the game, rewarding players with high level gear for defeating insanely hard bosses using smaller groups.
An official release date for the patch still has to be announced, but if you want to try it before it comes out, you should sign up for the Public Beta Test Realms as the update is already live there.
