I am pretty sure this isn’t a public relations action of Blizzard. But since I’ve been playing WoW too, I’m definitely sure this is a WoW Horde player’s drawing. What we have here is a called a troll shaman.
I have a night elf rogue (Ucigasa) and a gnome warlock (Ucilock). They are both Alliance (the opposing faction for Horde).
Even so … I do like how how this troll shaman is painted :)
