Free mount, Felsteed! =)
I'm trying to remember what the level 40 AoE fear spell is called.. Howl of Terror or something. That looks badass.
And a pain-in-the-ass-to-get epic mount: Dreadsteed. I'd MUCH rather pay 900g than work as hard as you have to for that mount. However, it looks badass, so I think I'd tell 900g for a stupid horse to go screw itself.
And yes, it's Howl of Terror. It would rock if it didn't have a 2.5s cast time. With that long, it makes it REALLY hard to time correctly.
