I am really having trouoble trying to find what class i like and what i want to lvl. Right now i have a 63 human warlock, that i adore! :)  But i do have to say that i am getting quite bored. Ive kind of narrowed it down to a rogue, a shammy, a pally, or a mage.  But that thing is i dont know if i want to wear cloth again. Im just kinda stuck and i would really appriciate it if someone could help me out with some good responses :D

here is a simple math lesson that id like to teach u.

pally + anything = 3rd best at everything that you could do
shammy + elem = loads of damage
mage + fire = even more damage but less fancy trics
rogue + sub = damage like a meele frost mage with loads of fancy or wonderful tricks

and my favorite

1 + 1 =2
