Destiny PSA: don't do the Nightfall until Tuesday's patch drops
Destiny players: do yourself a favour and don't do the Nightfall right after reset.
Destiny Year Two doesn't provide an XP buff after the Nightfall, but many players still step up to the challenge as the first item on their weekly to-do list, right after reset.
This week, you should hold off.
As promised, Bungie making adjustments to Nightfall rewards so they don't, well, suck; no more receiving a Rare and a Mote of Light, with any luck. This change arrives in a patch arriving at about 10:00am PT Tuesday.
So if you want some decent loot (Exotics and Legendaries for preference) your best bet is to sit tight for the update.
