Yes, stones should be a feature that is buyable. I would hate having to look for stones. That would be wasted effort.
Also, there should be a easier way to get pokemon that evolve through trades. I don't want someone stealing my pokemon that evolves in a trade.
I don't know what you mean by Q.Q less.
If you don't have any friends in PU that you can trust with your pokemon, then maybe you are doing something wrong
I don't really go out of my way to try and "collect 'em all" in the Pokemon games. Is that just me?
