Very useful for match game Nightfalls, and Field Prep/Demolitionist is a good combination that sets it apart from 21%, especially for warlocks who like top tree voidwalker. And it's hilarious that some people complain about the grind, just slap on a heavy finisher mod from the season artifact if ammo finder/scavenger mods aren't enough, and run some strikes.

Field prep/demolitionist are my go to for nightfall runs. 21% is more versatile, but unlike 21%, you can't abuse your armament mods to use it like a primary weapon.

Love it

Slightly worse than 21% but not by much. It's a good tool to have for match game nightfalls and other content that requires to deal with solar shields. Otherwise just bring 21%. Very good LMG.

Trash no worth the grind when Delirium does what edgewise does but better Delirium is worth the grind

WEAK! Not worth the grind.

Good for grenade kill bounties and nothing else

Field Prep is not to be underestimated. With stacked reserves mods and ammo finder you can run this as a primary and use your other two slots for a sniper and a shotgun or two grenade launchers if you're a madman. You may want to throw on a counterbalance mod to get a more predictable 65 recoil direction for console use but if you're willing to deal with the kick then the best bet will be rampage spec to extend the duration just a little bit.
