This is the #1 pet peeve for me. I'll leave it at that so I dont flame the post and call Blizz lazy (whoops I did it!). Anyways its been said Blizz would never make a class only mount for locks. First this would cause a QQ and a cry "i want a mount for my class". Then Blizz would have to re-skinn another drake (dangit it! did it again!). So pretty much boys and girls it the "well if johnnie has it, why can't I get one" arguement.
As a lock I dont care about a lock only mount anymore or green fire. I would rather Blizz work on our class..insert complaint here.....
