My friends and I have noticed that this game lacks an efficient or simplified way to train EV's, similar to the Super Training offered in later-generation games on the DS console. Right now it's grindy and down-right boring, but necessary for a good team later on. I was told to place the idea on a suggestion forum post. We proposed that, if the mini-game itself is out of the question for the Devs to produce, that there be some alternative, perhaps a building or zone in the Elite 4 area that allows for us to enter a zone that only drops pokemon of a certain EV return. So if we can't use the mini-game, at least we could have a simplified variant. The pokemon fought would give no Exp, but offer a quicker option for the EV training. It would offer an option for a time-sink for players and perhaps could be an alternative method to LOWER EVs besides just focusing on berry collection, not to devalue the worth of the Berry League feature. Hopefully this idea is useful, as I didn't see any similar posts when I did a search in the suggestions. Any other ideas will be welcome! Thanks for the time reading, devs.
TL;DR : Super Training please.
