You think you want this, until you get killed in a firefight due to something that was out of your control, which will add frustration.
It might work in an open-world survival game, but not in this.
Once in a while the Rocket Barrage will simply fail to deploy. It will be called in and be confirmed, you'll hear the rockets being fired in the distance but they never arrive. I have no idea what causes it but it is super annoying to have your most powerful ordinance bug out, often.
Movement, yet again, feels SUPER floaty when you're wearing heavy armor or a heavy carrier. Changing direction feels like you're walking on ice. It feels horrible.
Aiming down sights with a grenade launcher doesn't work most of the time, it just sort of zooms in the screen instead of aiming, and the grenade launcher model on the gun jumps up and down.
The current TTK is basically good for casuals and new players. In the old Insurgency, a good player with superior reactions and aim could dominate a server. And that is how it should be, in my opinion. Pure skill should always be rewarded.
I prefer the G3, simply because when you shoot dudes with it, they go down.
