I can understand your concern to some extent but how would you matchmake it?It looks like it would be quite complicated to me:Who would be the host (key owner) of the Chaos Trials played through the matchmaking?Could people just queue without having a key? Would you have to select a key to queue?Since it's a mode with modifiers that can greatly alter the playstyle or strategy used, how could anyone prepare themselves to tackle the Matchmade key? Would you make a different queue for each difficulty?Since it's also divided in tiers, how would you restrict or create the teams? Since a Tier 1 Rift Lord Key might be doable for lvl 70s but would probably be (almost) impossible for lvl 70s to play a Key Tier 7-8+
Sorry as such a new player to Chaos Trials (PS4 just released them) I did not realize there were so many considerations. I will withdraw my request and ask if maybe the chaos trial description could be a bit clearer and explain the trials are for friend invites only. Thank You.
