Hunts are a great idea.
However the implementation is a bit wrong as the rewards are too high.

Many players are making it their main focus. Thats not how it should be.

If you stumble across a mark and could either solo a B mark, or shout for a bit of help for a A or S from players in that zone.
That would would be good.

But we have teams of players who are doing nothing but swarming on every mark. Destroying it in seconds. Not as intended.

Reduce the reward so although beneficial, it's not the main focus. Keep people doing raids and dungeons.
