Ooh, I hope so! Completely forgot about contests. Have they appeared since R/S/E?
It may be a problem with the remakes being in the same generation as X/Y, as it would be easy to evolve Feebas in another game and trade it over.
They haven't appeared in their original (and what I feel is the best) format since R/S/E.
Contests SHOULD return. It was originally introduced in this region after all. And by contests, it should be the original format -- the one with Appeals. I find it more fun than Dancing.
As for Feebas, I think both the Max Beauty method and Prism Scale method would still be utilized. I don't see why not.
Are there any other Pokemon that evolve to the same Pokemon by two different methods?
