If were going to start with lists..
5: Warlock: Fear, dot dot dot, fear, /cackle...
4: Preist: They are boring, fun class higher up apparently, but I can't get one past 22 to save my life.
3: Warrior: Boring... boring... oh ya... boring... and if your not prot, you usually don't get anything done, because there's like 500 other Fury warrior competeing with you, and Arms is just pointless at 80 from what I've been told
2: Hunters: Played one to 70, it's still rotting at 70, No ambition to play him anymore, and I wouldn't want to get the "Hunter" label stamped on my forehead either...
1: Death Knights: Ok, Now, I <3 my own DK, she's sitting at level 63 in Zangarmarsh, but really, Death Grip needs a pvp nerf, so does chains of ice orwahtever it's called, It's really annoying to get hit by that spell four times in a row, from two dks as they jump around you laughing as they slowly pick you apparart, or quickly if your not a tanking specc -_-
IMO: Death Knights are Wonderful for PvE, very helpful and all, but then you have your donalds, your morons (Who almost fit donalds, but not quite), your l33ts, ect. ect, this class, due to starting at 55 and being one of the few classes that can go from being insane dps to being impossible to kill in two seconds flat, attracts the most bad players and such, and the large percentage of horrible and immature players playing this class give it a really bad reputation
Druids would be just as bad IMO if they started at 55, but most people are to lazy to level, thus they pick DKs...
