And earlier today Doubleagent-Mannoroth hit level 90 and became the first and only character (he’s a Pandaren Shaman) in World of Warcraft to level up to max level without choosing a faction (neither Alliance nor Horde). Took a long while to achieve but that’s one hell of an achievement, congratulations Doubleagent, For the neutral!

And here is his thread about reaching level 90 (why and how he did it):
This is pretty awesome. I love seeing the different ways people enjoy this game. Good on him :).
