The only way I'll ever support a timed spawn NM is if its a world spawn that can be challenged by anyone and everyone at the same time. It could be a massive creature capable of tearing people to pieces if fought by only one or two alliances. Kinda like early besieged where monsters where impossible to kill alone. As for drops have it drop from the nm where it can be lotted by anyone who participated along with a personal chest with loot related to that person's merits in battle. Or hell introduce a type of point system.
