We mention a ninja of the Onyxia mount in this week's Guildwatch, and while researching that, some other forum threads came up, including these two, both from General, where people say with conviction that given the chance, they'd take the Onyxia mount and never look back. They have a point -- it's one of the rarest random mounts in the game, on a raid that's definitely PuG-able. Chances are low that you'll ever see it, much less win it on a random roll, and so for a lot of people, it'd be worth the namechange and the server transfer you'd have to pay to escape your new ninja reputation.
Personally, I wouldn't do it, but that's really only because I know there are lots of rare mounts in the game that I'll never get (sigh, Red Proto-drake, I covet you), and one more isn't that big a deal. Not to mention that I like the guilds I'm in and the people I play with, and who knows what they'd think of me if I stole the mount from them or someone else. But not everyone feels the way I do, I'm sure, so let's ask: if you had the chance, in a PuG or a guild run, to steal the Onyxia mount as your own, would you take it? And if you would, is it just because it's so rare and special?
