Co Op / Multiplayer missions in Maps

Hello!

For my entire time playing the game in both seasons I have had a few friends I normally hop around with. While I think the vast majority of 0.2 has been significantly improved Campaign & endgame wise from 0.1, the changes to the Corruption nexus questlines make multiplayer inefficient.

I am hoping there can be some sort of change to allow for quest completion on the corrupted Nexus' atlas passive books to be given out to every party member present in the map as long as they are eligible to receive it.

Thanks.
