>>38118249I don't know about best, but I hated how bland and boring Alola's Elite Four was, you can literally tell they planed it last minute and weren't even thinking about adding it in the game. Considering they already changed the gym formula in the games, they should have come with something different too for the last part of the game.
Overall, I feel like Alola was full of good ideas and concepts that never actually came to life, and they don't have a single excuse for that. They had a whole fucking year to fix things with USM, and they didn't. With pointless characters like Mina and Ryuki, they should have had a much better Elite Four, if it was ever the plan to make one.
