btw i just hit rank 11 so the question becomes............
which to use! i don't think a random mount selector exists (that i could find, anyway) so i am torn. i ranked up for the wolf but the kodo and raptor are both very classy as well. i don't really care for the horse and it's a little too typical anyway seeing as how i am actually undead (though i kind of fucked up the angle on the horse screenshot so it doesn't look QUITE SO GAY ingame but still). i don't want to go into my bags and choose a different one every time though so HMMMM.
also as it turns out you don't even need exalted to buy or ride any of them. i thought i'd only be able to use the horse and wolf since i'm undead and only exalted with orgrimmar, but i just randomly decided to try using the raptor/kodo and was surprised that they worked. i guess with the riding skill changes last patch to a general 75/150 thing and not horse/tiger/whatever else riding, you only need to be exalted to purchase the mounts themselves, and that apparently does not apply to the pvp mounts. just fyi in case anyone did not know this and was about to farm a bunch of runecloth to get exalted with one of the cities. i feel kind of bad since i think bjb did exactly this and if he'd just gotten his nightsaber post 1.12 (or did he?) it would've saved him a lot of time/money. i hope they don't change it, because i like the idea of having a bunch of different mounts and probably wouldn't bother getting exalted with thunder bluff/darkspear trolls if i had to.
