All rotom forms. more dungeons, but not so many hard ones like destiny tower. i quiver by the looks of it.
i like different missions. maybe saving 'common' legendaries will be cool. Also an item to increase accuracy will be awesome too!
Oh yes, i prefer the hunger meter for ghost/darkrai(i think) don't go down as fast as normal pokemon using the mobile scarf (i think), when going through walls. since my team has pokemon that able to phase through walls without getting hungry fast, it should be the same as for the leader.
