There are A ranks that will award people who get full "attendance" with 40 Allied Seals while S ranks give 100 seals.
A ranks are on 1 hr timers to force a spawn.
S ranks are on a 24hr? timer to force a spawn, though must be triggered by spawn condition (moon phase, completing all zone's fates in 1 hr, etc)?
These require parties to kill properly. It also requires you to be in the zone and actively on the mob (lots of damage, tank agro or healer agro).
Healers will spam their high healer agro stuff on tanks as well as needing to drop an aero or two on the mob (WHm especially useful. Divine Seal+ Medica II, Cure 3 bombs.)
