Personally I see the problem in the whole design of the hunts. From a feature that could have been challenging it degenerated to midless zergfest for free marks whenever some 3rd party app tells you to go gather them and that also created the issue with "early pulling".


Hunts would be much better:

If they had per person CD, instead of long respawn times.

If they were spawned by time limited quests, with only the person and group who spawned it being able to attack the boss.

Something like an open world raids would be much better imo.
