Who else wants Lorewalker Cho to follow Alliance and Horde campaigns from now on wherever they go? Once we finish up with Pandaren lore in MoP, just have him be a chronicler of the rest of the world or whatever worlds we go to in the future.
I really like Lorewalker Cho and want to see him stay relevant to the story. If they aren't going to bring up Aysa or Ji in the future after MoP we'll need someone to keep the Pandaren relevant as a race, and I like Cho more than either of them anyway.
