^ there was a lengthy discussion about amiibo over at BotW, and in the end they just made subcategories for with and without.

It seems like people fear that Amiibo allow you to cheese the run too easily, which may make it too uninteresting. The Any% category under misc allows for them, so I guess that's where people can experiment with Amiibo and see if it's fun. This could then possibly be extended throughout all the other categories.
