I think the Hunt system is working perfectly. I've not noticed any significant increase in Queue times for dungeons (I haven't reduced that part of my game play at all), I've earned 3 sands and 1 oil since it started and have accelerated my Alexandrite acquisition. Our server has a main, huge temporary hunt LS that is wiped and regenerated each day. While there is some frustration at times with early pulls, for the most part, it works fantastic.
The only issue is with the hunt mob disappearing from screen when there are so many PCs gathering. A change to ensure that the target, focus target and party characters have highest rendering priority would be a great change.
Keep up the great work on content development SE!
