If you run too far or skip areas in Nightfalls you can make champions despawn. If you make champions despawn it counts as not killing them and therefore you cannot get platinum. If you dont get platinum you do not get ANY nightfall rewards. No weapon, no cores, no prisms, no shards, NOTHING.
PLEASE STOP!!!!!
We are not playing these Nightfalls for the end of strike chest for 3 legendary shards. We are doing them for the WEAPONS.
The only time people should be doing lower tier nf for loot is when trying to get random drops for soft or hard cap. Even then, there are more efficient ways to do that.
Any efficient gamer only does lower tier nf for powerfuls, pinnacles, bounties, rep gain, quests, or challenges. As such, we want to get it done as quickly as possible.
If you are inefficiently doing lower tier nf for actual nf loot… this is a you problem.
