I'm not sure if this has been posted elsewhere, if so feel free to lock/flame lol
Anyway, i know this to be working on DS WoW, i'm not sure where else it will work but they're up to date with Ascent so who knows
1. Anyway, what you do is get on your mount (the faster the better).
2. Once you're on your mount ride until you find a chair of some sort.
3. Click to sit on the chair while still on your mount.
4. And walla, you now are still running at the same speed of the mount you were on and now are able to use of all your abilities.
