I think your suggestions are good except for the last in which I agree with Hulvien. The hunts weren't intended to be an all-inclusive event as much as FATEs are. However, I think there are probably ways we could discourage people from over hunting to allow for other players to stumble upon the mobs as it were intended. Maybe limiting it so that you're only rewarded for one rank per week? But then again I feel that that detracts from the original spirit of the idea also. I just hope it's not a matter of waiting it out til the majority of the population has grown bored of this content.
