Imagine one day Blizzard says, “Yeah, fine. Whatever. Here’s a saddle and you only get ONE PER ACCOUNT. You may place it on whatever you like, and it’ll be your mount.”
What do you saddle as your mount?
I’ll go first and say that I would saddle a Devilsaur from the Isle of Thunder…
… but something else might come to mind later on!
You, big boy.
Yee-haw.
B-but! 
My wife already has me as her…
I’m already soulbound! You have to choose something else!
The question isn’t what, but whom 
You stay away from Wrathion!
He belongs to Anduin!
But who does anduin belong to?
This thread has taken an unexpected turn!
Xal’atath.
Always thought the first boss in Nighthold would make an excellent mount.
A Tauren male, for reasons…
Daumyr. She should have been our Legion class mount.
Big ol zeplin.
Either one.
The undercity zeplin has been out of commission so easy grab
rabbit.
of course.
Nah, I figured this went pretty much where expected (giggle).
Actually, I’m changing my pick. I choose to saddle the Vindicaar.
Space adventures here I come!
I find the nearest gnome mage. He can make portals and carry me wherever I like. He would make me food and drink whenever I want it.
I always loved the idea of being carried on a litter borne by six gnome slaves…
Gallywix. It would be funny
In the holiday spirit:
On Blastbolt, on Turnwrench, on Fusebomb, on Zappbrain!
On Nosepipe, on Speedslug, on Jetboot, and Greasestain!
Well, they just gave us Deathwing, so I think I’ll have to go with Alexstrasza. Sorry, not sorry.
