My biggest WTF moment was when I talked my friend into playing WoW for the first time.  So, I get this guy all pumped about playing some WoW.  He goes out buys a computer, buys WoW, and sets himself up for WoW.  So he's in my room with his computer and we are sharing internet.  He makes his character and logs in.  Immediatley when he logs in he turns to me and says "Dude I just died".  I, having played for about a year and some odd months now, sit back in my chair and think "WTF".  He resses and immediately dies again.  So now I'm really thinking "WTF"!  Come to find out, there was a lvl 70 Horde Rogue just sitting there at the Starting Zone for the humans, backstabbing lvl 1's.  I'm like are you serious?  Who gets off on that? Although it's pretty funny...lol =P.  So me being a lvl 70 SPriest, I grab a friend lvl 70 Hunter and we go and run this guy outta town til he logs lol.
