I think that was a good decision but we need a way to get the mega stone without waiting a whole year. Maybe they can make another quest that is available for the rest of the year.
Please don't make mega stone quests bound to event map. It feels awful buying a poke and having to wait one year to use the poke in pvp. That's such a tilter and not needed to enjoy the game. Mega stone quests for pvp mega shouldn't be limited to certain times.
My suggestion is to limit legendary pokemon in pvp to one per team. Facing teams stacked with legendary just doesnt feel right and takes alot of fun away in my opinion. what are your thoughts on that?
