Not Yet

The Ashen Liniment I picked up in Korthia makes Tyrael's Charger look like the Angel of Death. I tried out several mounts with the buff, but this was my favorite.
Also, the drop rate for the Bonehoof Tauralus is even worse than I thought. I have Neena with me daily and I even remember (most of the time) to have her loot for me instead of throwing my loot-a-rang. But I'm still pretty sure I'm never going to get that mount that I don't even want for any reason other than:

1. It's close by
2. I leveled my Abomination Factory
3. I collected Neena

And even if the mount isn't worth the amount of work required to get it, at least it will be something in return for the hassle.  It does give me a chance to try out toys and clean out my bags while I'm just standing around, though.
