I don't see why people can't understand him, I mean.. c'mon.. Most of you play WoW, and everyone knows there are SOME people that don't type very well. You just have to get used to it, what he's saying is:
1. Queue up for your preferred BG/Arena
2. At the end of said BG/Arena, don't have your pet dead, and make sure it's out.
3. When you come out of the BG/Arena, you will be mounted and your pet will be standing next to you, like it used too, so you're mounted with a pet out.
4. Enjoy.
(I haven't tested this, so please excuse me if it doesn't work)
