I don't agree. Right now you can do heroic dungeons and raids (where the most rare drops come from only once a day(dungeons) or week (raids)
if you have multiple characters, you can multiply that chance with the number of character you have at the appropriate level if you really want the mount badly.
more chances to get it in a lockout = faster drop overall = more mounts overall
Edit: it didn't make sense that paladins were in a quite advantaged position with access to 3 or 4 extra mounts compared to other classes.
(and before you start whining "well level one then", ask yourself the question why paladins should have those class specific mounts, and other classes cannot have such things...)
Everytime I see someone talking about "rouge", i have the urge to say " yes we are overpowdered"...
