your friends might be completely off-base. Onlineuniversity.net put together a graphic comparing World of Warcraft to the popular dating site Match.com, and the results come out pretty firmly in favor of blood elves.
So how does it look? According to the graphic, World of Warcraft has more than 10 times as many people involved as Match.com, and people sink more time into online gaming than any online dating site. There's also a number of factors that suggest slaughtering virtual trolls as a better way to bond than a cup of coffee. So while it's still probably bad form to hit on your raid leader between pulls, maybe you're not entirely off the mark. Unless she's married.
