If your a rogue you have the ability in your Combat talent tree called: Unfair Advantage.
This is more or less an exploit but I didn't feel the need to post it in the exploit section. I also searched for a bit and didn't find this posted before, but if it was, I apologize in advance.
Anyways...
This ability allows you to swing at a target with 100% of your main hand damage if you dodge one of their attacks. If your on your mount and you dodge an attack, you hit them back with your main hand damage and you don't dismount. This is not useless, if your running a nooby friend of yours somewhere you can run ahead of them on your mount and clear everything super fast without getting dismounted before they get there.
