According to my last check on Wowhead, I believe the drop rate is around 0.3%, and I think the Kodo/Rams were around 1.3% - 1.5%, so it is drastically lower. I would not attempt to get five of them. Most likely pick your favorite toon and go from there.

heh, that's what I do. Anything that's easier to obtain, I do on all five, but for purely achievement purposes, or showing off, Arlassa gets all of the hard-to-find/get items and achievements.

I got my druid team to 77 yesterday. I'm going to get them up to 80 before Hallow's End, and hopefully get my Mages up to 75 before it, too. That'll be 20 summons a day.

Even with that amount of summons, who knows if the mount will drop. And for Brewfest, I ran with a guildy tank and healer to make the fights a bit easier for me, since I didn't have a tank class leveled up. And I just know that if I bring them along for Hallow's End, one of them will end up with the mount, if it does happen to drop.

It's going to be a close call, taking a crash course in bear tanking with purely AH bought tank gear and only a week's worth of time to proactice. And that's only if I decide to not work on the mages.

I'm not terribly optimistic about getting this mount, sadly.
