>>53727139I think the big issue is having multiple conspicuous locked doors slapped into the middle of a route when the player never actually gains the ability to go into any but one of them. for how much people complain about the galar power plant on that one route, at least it doesn't cocktease you with a secret that doesn't actually exist.
plus the other buildings are pretty visually distinct from the power plant that we actually enter. while it could easily end up being samey with the one that was made, it just as easily could have just as easily been made distinct.
