I have no idea. Never played much of it.The AI would control your fight, maybe.
But it would have to be a live battle. What if you run into battle while away?
Reading about that stalker mode, I'm seeing some flaws in that. What if the person who's being stalked doesn't come back on and post for ages, that would stop the stalker from making any progress. Perhaps there should be a time limit where the AI would take over. The time zone difference between us is a big limit here.
Also I think it would be cool to throw tournaments at different cities at set times.
