i noticed that if you have a team and everybody is making a different bounty legenderys still drop for everybody
so if you make a 4player team split up at making the bounties you are faster at getting your horadrim cage and you still dont lose you leg drops (if you go to the waypoints after you cleared the act, just press the map button to look for leg-indicator)
2second thing i noticed that you still get xp if you wait in town while your team is killing stuff in the netherportal
i am not so sure if this is intended
