Always when I go to bosses I never understand how they work. For example, Urmahlullu the Weakened, a couple times I was there with different teams and sometimes the most high levels get rewards but other times the ED's get the best rewards. The same thing happens with the new bosses from Feaster of Souls Quests and HOD bosses. So I wonder ¿What bosses that are part of the Reward System work with the cooperative loot system?
Thanks in advance.
If you feel like I need to put a better explanation, please feel free to tell me I hope I explain myself well.
