Blizzard has announced today the next phase of the Legion pre-expansion will be the launch of the demon hunters! Demon hunters are the new hero class that are set to go live for everyone when Legion drops August 30th, but players who pre-purchased Legion will get early access starting August 9th. Demon hunters start at level 98, and will only be playable with either Night Elves or Blood Elves.
The demon hunter class will be split into two different specs. The havoc demon hunter will be the dps spec, while the vengeance demon hunter will be the tanking spec. Here is some basic information on the class from the Blizzard World of Warcraft site.
Warglaives, Daggers, Fist Weapons, One-Handed Axes, One-Handed Swords
