Now you can be a Hanzo main in two games. At BlizzCon 2017 today, Blizzard announced officially that Overwatch's Hanzo and World of Warcraft's Alextrasza are the next heroes coming to the MOBA, along with a new event, Dragons of the Nexus.

Alextrasza is a "versatile ranged support who manipulates her life energy to heal her allies," and can transform into a dragon with her 'Dragon Queen' ability. If you aren't familiar with the character, she's a big part of WoW lore. Hanzo, meanwhile, is of course a "nimble ranged assassin" as he is in Overwatch.
