Last week Massively showed the readers a research report done at gamerDNA regarding MMO players' Bartle Type and how it influences their Warhammer Online class choices. In the comments at their site, many asked if this could be done for other games as well, namely World of Warcraft.
While not as clearly-defined as the WAR/Bartle results, this report shows some interesting statistics relating to WoW players and their gender, personality, class type and more. Keep in mind though that these results are based on around 45k+ members at gamerDNA who play WoW, not every single player out there. Even so, it's always enlightening to see these things in solid numbers.
