For example, on Liberty Island's page, it says that you can get Victini, but it doesn't specify on Liberty Island's page or Victini's page that you can only get to Liberty Island through the use of an event item, which could be misleading. The same applies to the pages on Navel Rock, Birth Island, Southern Island, Faraway Island, and most other pages on event exclusive areas. I think it'd be useful if it said if that the area was event exclusive. There are a few pages that do specify that you need an event item, for example, Flower Paradise, so I don't see why these other pages say that you need an event item.
