Returning player

I was wondering if there was trading for seasonal. I seen its BoA but all I see is people saying console. All the post I see are old. Also if there is not open trade. If I was in a party is it instanced loot?

Trading is the same for season or non-season. Legendaries can only be traded among players in the same game, and for 2 hours afterward. Otherwise they are bound to account.

If in a party does everyone get there own loot or is it who ever picks up first?

Everyone gets their own loot.

I noticed you have 3 lvl 60 heroes with paragon.
you need ROS (reaper of souls) expansion to play end game content. without ros you wont be able to join any groups, run rifts/grifts etc.
