Gyrfalcons needs more work done in general. Nearly infinite volatile rounds is great, especially on Collective, Graviton, Monarque, and any weapon with Destabilizing Rounds. Though I feel needing to get a finisher while invisible is a bit much when you might not have invis at any opportunity, your team might take it from you, and if you do get it, the duration starts after you start the finisher instead of after you kill the enemy with it. That 5 second buff may only be available for a whole 2-3 seconds depending on your finisher.
