The first Legion beta build has been datamined by MMO-Champion and wowhead! You should definitely check out their full datamining pages, but here’s a highlight summary:
Be aware, spoilers after the break!
- MMO-C put up a lot of new models, such as a bird version of Lord Marrowgar and Bolvar!
- New maps have been added, including one that has Dalaran on top of Karazhan.
- Professions have many new item categories and possibly new sets
- Enchanting and Archaeology both get a new mount, demon hunters possibly 2 (unless blood elves and night elves each get a different mount)
- The Highbourne, Highmountain Tauren and Demons will be the new Archaeology factions
- Blacksmithing allows you to craft an item to increase your mount speed by 20%
- Gathering professions also have levels, like crafting, but to get buffs or extra materials from gathering
- All raid buffs have possibly been removed (they are currently removed from all pets)
- As expected, there are lots of class changes. Be sure to check them out for your class! For example for hunters spells like Aspect of the Cheetah and Tranquilizing Shot have been removed.
