I've always been kinda craving for a pokemon game where you can actually participate in a league tournament, just like how it has always been in the anime! Using only 3 pokemon in first preliminary rounds, and then using full party on later rounds, healing your party and option to be able to change your party before every round, different fields for each match and those fields giving advantage to specific types, battling against randomly generated trainers in preliminary rounds, but in the full party rounds battling against some important fix figures like your rival or some other strong trainer who had been collecting badges, as well as randomly generated trainers, and after finally becoming the winner of the tournament, gaining the right to challenge the Elite Four & Champion! Of course if this hasnt been in the cards for Ame from the get-go there is little chance this will be implemented.
