I'm pretty far in Master Quest Map now (in Hyrule Warriors (Wii U), that is; I haven't unlocked it in Hyrule Warriors Legends (3DS) yet). I have 12 blue squares and all of red squares yet to be played. Of the squares I cleared so far, 7 of them are "Don't get hit!" challenges, 3 being in Adventure Battles. There may be more coming, and it's getting a lot harder now, so I have to be prepared.
