This might sound kind of nooby, but honestly I rack up the kills and assists with it. Dexterity is really important for the AR, and when you combine a pulse grenade with AR fire it kills them very quickly.
I’m a massive fan of this grenade in dominion. Using a similar loadout except with the suppressor and sentry AA I can lock off entrances to the base for a precious few seconds while I take out the guy coming from the other door.
Another fun one is tossing one on the capture point as someone’s running up to capture/reclaim it. Admittedly using any grenade would do but having a a big bubble shield of hurt pop up is soooo much more satisfying.
