I second this idea, there actually is another thread posted on the general discussion side about this same topic, and it's one I hope gets some serious consideration from the devs. I was also thinking about how they could best implement restrictions so people don't abuse the hunts, and I was thinking that the hunts could have party size and level/rank restrictions and limit on how often you can get hunt marks, maybe something like they did in XI with conquest, hunts get updated 1x week, or maybe tie it to the guild leves and you can only undertake 1 hunt every 36hrs and you are only able to to do 1 zone. The rewards of course have to be worth it, kinda like the more popular enm's from XI.
