Datamining has uncovered the class selection for two of the four allied races slated for World of Warcraft: Battle for Azeroth, and it will likely not come as a substantial surprise. It looks like both Dark Iron Dwarves and Mag’har Orcs will have access to the same classes as their “parent” races, barring hero options; Dark Iron Dwarves can be everything aside from Demon Hunters, Death Knights, and Druids, while Mag’har Orcs also pass on Paladins and Warlocks. If you were hoping for any particularly odd options, you will be slightly disappointed.
The build also contains the usual assortment of new zones and new class changes, as well as a few new mounts hinting at factions or at what players can unlock via PvP. As with anything obtained via datamining, it’s subject to change in the future, but you can take this first look as a fairly reasonable indicator of what the future will hold.
