>>30524358Isle Evelup is inferior to super training. Isle ... whatever, the hotspring one, is inferior to actually hatching eggs or raising happiness yourself. However, taken as themselves, they're harmless. Just put your pokemon there while you're busy with other things so you can multitask. Only issue is the removal of super training, but that's another matter.
The bean island is okay, though I've never gotten a pokemon to stay. The berry island is very nice, I miss being able to customize the routes a little bit by planting berries like in Hoenn, but the island is very, very effective at putting out massive numbers of berries. And the exploration island is again very harmless, but not actually useful. Certainly no Sinnoh Underground, but it's not a replacement for that anyway since that's been gone forever. However, they should just let me buy fucking Ice Stones god fucking damnit I haven't seen one in a week of exploring that fucking cave.
