As a filthy casual I think the rewards being so good is a problem.

I don't know about your servers but on mine there's a lack of people in the second coil of bahamut because many people still haven't gotten around to beating the first coil. So in party finder people are constantly looking for more members to do the second coil with.

I don't have a coil group and usually just pug whenever I feel like it, but the sands of time, oils of time, and unidentified allagan tomestones should be an incentive for me to attempt to do coil, and find my own coil group so I can get stronger.

With the rewards from hunts though why would I bother with the stress of a coil group when I can basically get gear I want outside of high allagan? True if I care about bis I'd probably do coil more, but that's why I'm a filthy casual. :3
