They said that the loot would be shared. Technically, I thought it was like an individual roll for items per player, and you get to pick that and that only. That or randomly "roll" and assign items to one of the member of the group. It doesn't really matter how exactly, but I thought it was obvious that everyone get their share of the loot automatically, not "the one that kills it gets it".
Why? We always had rules in our LAN or private friendly games.
