Some dungeons have stuff like that, like Sunken Temple HM at the end where we press 3 switches which seemed kinda....um...boring. They were all next to each other and I thought it would've been more complex like the first Sunken Temple with the plates and pictures. Sastasha HM had just about no puzzles or mechanisms in it when the first one had the message at the beginning of the dungeon with a REALLY easy hint of what switch to press during the Coearl fight.
