There are some loadouts in nightfalls that simply outperform others, this is quite natural and is prevalent in most activities.
The team comp of izanagi-divinity-erianas is very effective at clearing champions due to the high damage and champion stagger properties. But now that nightfalls are excellent farming, running the same loadout over and over becomes very tedious.
Last season I ran about 200 nightfalls and my team refers to Erianas as "the soul crusher loadout" as you end up only using a primary for the entire run to conserve ammo. (Thank you bungie for increasing the reserves, this is less of an issue now).
Would it be possible to add champion stagger properties to underused exotics? Breath a bit of fresh air into both the nf meta and bring forward a couple underused pve assets.
For example:
Shield piece:
skyburners
Arbalest
Unstoppable:
Sturm + drang shield piece?
Whisper
Overload
Black talon
Fighting lion
