One of the reasons I enjoy these sort of games is because open world bosses have loot exclusive to them. Having a named drop that you have been farming from a named enemy out in the open world is such a cool feature that makes people want to keep logging into the game and explore older areas where these bosses spawn.
Please ensure that “solo” content that the devs say they will focus more on (as stated in Sept DEV VLOG) in the future has farmable bosses that have their own loot pool. Soul Trials for example HUGE missed opportunity you fight Apophis ONCE then get his one drop then DONE. We need more loopable content. Logging in to do craft cooldowns while waiting for OPR/Expeditions is not enough to keep coming back and logging in.
