Right, I found this video that I want to share with you.
This video contains footage of a level 60 Warlock who owns several diffirent level 70 in season 2 gear.

I don't know if I should laugh or cry, but one thing is for sure. The warlock class is way to over powered as it is.

I like his pro tip at the end about getting high damage done in battlegrounds..

1 2 3 tab 1 2 3 tab 1 2 3 tab etc etc.

Uhh, no

Hes level 70,
SL / SL is 61 points.

He is just wearing level 60 gear

The video is also very old. I think it was made previous to the massive nerf hit that Warlocks got. They are still overpowered but classes like Hunters and Warriors have, in effect, taken over as the kings/queens of imba-ness.

i would own his ass hard with my bm hunter today, but since this vid is old warlocks arent so much overpowered anymore.

tbh the word OP is thrown around alot these days :P i play rogue/mage and really if u just do it right u can beat any class. Its just a mather of skill ^^

I totally agree with XforceLB it is truely a matter of skill... i would allmost bet that you have two level 70's dueling one have absolutely no skill at all and the other have extremly alot skill. Now the one with no skill have good gear and the skilled have bad gear. Who would win? i am betting on the one with skill.

I play a shadow priest and I consistently win over most classes if I'm prepared properly.  If I'm not prepared, rogues, hunters, and warriors run over me.
