So i think that the game lacks post game features.
(other than pvp and stuff)
I suggest to add a boss. It could be the character we play as in the official games.
(like Red from Pokemon Fire red and Leaf green) and make them verry hard to defeat (perfect ev and ivs And Balanced Team)
And have a good Prize if we defeat them.
I personally would like to fight the character we play as in Pokemon Black and White 2.
I think it would be Possible as the recent event has that. Like the gym leaders and elite four.
Thats It
thanks!
