Remember when they speculated about WoD being tied with the Warcraft movie? Do you think it's possible WC3 Reforged is influencing them to revisit old WC3 units for potential new classes, class skins and/or specs?
Shadow Hunter
Dark Ranger
Blademaster
Tinker
etc
I mean I've been personally waiting to play a proper Shadow Hunter or Dark Ranger since like 2004.
