Hello guys.
I just started playing this game, and I know that only one Arceus, Rayquaza, and so on, exists in the whole server. I also know that, once you catch one of them, you can't travel in any other way than walking, you can't move through regions and you have to accept and win all the battle requests in order to maintain it. And if you log out, you lose it too.
So... I was wondering, why even bother to catch one? You can barely do anything with it, right? Or am I missing something?
