I just tried to do Aurion (a 1385 ilvl field boss) and was unable to complete it. I was put into channel 2 and and we had about 10 players with ch1 being full and unable to be joined. We were unable to complete the fight even with some channel 1 players joining mid way though the fight. I believe the bosses are not scaled by player count and if you are tossed into an underpopulated channel it is impossible to kill the boss. The boss enters berserk after 20 minutes and continuously wipes the party. It then resets to full hp about 3 mins after going berserk. This is also the case with chaos gates. The gates are not scaled. If you arrive late and attempt the dungeon as 10/30, you will fail. Additionally, Procyon’s compass will mark the chaos gate as claimed even when you haven’t received any rewards.
Amazon Games please make co-op PVE scale with player count.
