:/ That's silly. I'm all for making the legendary Pokemon more difficult to catch, but to bar them completely just seems to kill the spirit of Pokemon.
Did you make your text speed faster? I find it to be acceptable, since that's how it is in the games.
I believe there's talk among the devs to make the Pokemon center automatically heal your Pokemon when you walk in. But it's just talk. Nothing has been confirmed or denied from what I've seen.
