That's why I suggested a spin-off, don't need necessarily to be Kanto. Just limit the numbers of species. But I think Kanto would be reasonable because that's where started the series, then the following regions for each sequel.
I see. The problem was not in using the abilities in the world, the problem was that is consuming a slot that could be using for a good ability in battle. That's pretty easy to solve, just make an extra slot for the non battle abilities (an "action" button?).
