Making all mounts DR able doesn't help my motion sickness. Seriously, if you think they will invest the time and resources to enable 900 mounts and redo all zones for that, I don't know what to tell you.
Blizzard always give with one hand, then take with the other, you know Hazzikostas is lying as his lips are moving.
Either way, it's time to move on, so I'll wish you all good luck, merry Xmas and a happy new year.
