People whining about Coil just want to be geared out in a week so they can whine they have nothing left to do...

On topic however, some FATEs do have slightly hefty timers on them. It would definitely be nice if there were triggers for at least the quest-tied FATEs. Could even retain a spawn window to avoid FATEs being chain spawned and blocking other FATEs. Even a three hour window doesn't seem that bad if you KNOW if you go out there at X time and satisfy X condition you'll get your FATE to spawn.
