Radiant Light currently confers its bonus effect at the completion of an often grueling Nightfall Mission. That effect lasts until the Weekly Reset when the next set of Weekly Missions is put into play. I think the effect should last a fixed amount of time so that everyone can enjoy the same period of the effect regardless of when they complete the Nightfall mission. Seriously, it should be self-evident why this is a bad way to handle this mechanic - any mechanic - by ending it on a particular day instead of after a duration period. The guy that has his buddies all ready for the new Nightfall mission and completes it that day stands to gain that effect for an entire [i]week[/i], but the guy that finally manages to get the job done two days before the Weekly Reset gains the Radiant Light effect for a mere two days. Is the problem here not totally, ridiculously self-evident? On top of the readily apparent problem of not receiving equal pay for equal work, as it were, it has the secondary effect of further rewarding and reinforcing better networked players' progress through Destiny, while giving the shaft and a slap across the face of the late-comers for the Weekly Nightfall, who are folks likely having trouble with the Strike and could really use that Radiant Light bonus, but will receive the benefits for incredibly less time. We know there are Cooldown timers in effect in a few areas of the game, with Ammo resupply packs and Glimmer boosters. An effect timer could probably be very easily applied to the Radiant Light effect, and it freakin' should be. Parity, Bungie. If you slog through Nightfall and come out a winner, you should enjoy your Radiant Light as long as any other guy, regardless of what day of the week you managed to emerge victorious.
