I guess maybe that the FATE couldn't possibly respawn within the 15 minute window plus whatever the cooldown was, even if it was completed.

Like, if it spawned at 8:00, would normally end at 8:15, lets assume a 5 minute cooldown, and it could start respawning at 8:20.

With the change, if it spawned at 8:00, would normally end at 8:10, and could respawn at 8:15, which would be more frequently.

This would only make sense if the 'cooldown' period, whatever it is, didn't start until the initial ending time, instead of right when the FATE gets completed.

And that would only make sense if trying to fiddle with their FATE system would cause more problems then it would fix.

Sorry, just kinda thinktyping to myself out loud.
