You're literally the worst Death Knight I have ever laid eyes upon. To see you have a 2500 tabard makes me want to gouge my eyes out. I honestly believe you bought your account.
And let me take a wild fucking guess as to what you're currently playing in 2s. Reminds me of that double blood DK team comprised of two 1500 Death Knights about 2 seasons ago that was top of the ladder above 2500 because of how ridiculous blood was. I believe it was during the introduction of "The Crowd Chooses You". Not sure, don't really remember.
tyvm mate <3edit: does it have to be King Mosh or any other devilosaurs will do? found an elite devilosaur and tamed him but not sure if the rare one has something special or not.
Hunter pets from the same class (Devilsaurs) but with different models (red dino vs blue dino) haven't had special traits for a long, long time. Basically what I'm trying to say is, all Devilsaurs will bring the same critical strike buff in Terrifying Roar, and mortal strike in Monstrous Bite. You can familiarize yourself with the different pets here: http://www.wowhead.com/pets
BE has one of the few blanket silences left in the game.
Undead still has one of the most game breaking racials in the game in WotF, even after all the nerfs.
Orc still brings great damage, and might actually be better than human for lock since the new [human] pvp trinkets seem like ass.
Rating doesn't mean shit, the people you play with make WoW fun. If you can't find yourself people that you enjoy playing with, grinding rating will be very painful and unfulfilling. Think about it, ebola is going to bring about zombie doomsday, do you really want to spend your last days playing a shit game, with people you don't give a shit about?
