No to shared loot drops simply because of the fact that armor is specific to class. Also, no to the maps. It's gratifying to explore and learn how and where to go on your own and not be the slave of the "M" button (for PC MMORPG players). Exploring isn't fun in the slightest when the purpose is to simply clear up a large, shaded map. I liked having to learn how to get to, say, the Forgotten Shore and The Divide. The map system found in today's MMO's needs to die in a fire, and perhaps Destiny will be the beginning of this.
