How about instead of having the city areas in the back of the dungeon and the poison prison, we have a captain spawn after so many kills of other stuff in there. Basically if someone is in killing the mages after 40-50 mage kills a captain spawns in that room with them and they would have to kill it to reset the mage spawn. This would keep the captains relevant and also keep people from afking the rooms. Its same idea that like old haven has where after you kill so many undead the defiler spawns. Then they could even add something like after so many captains are killed the lighthouse appears in the circular room near the entrance and people could kill it for bonus drops and it would be like a fun pvp spot as well on fel side like the harrower.
