The only reason you get 1 star is because I cannot vote 0. The only thing I want to see be changed about killstreaks is giving the Assault Juggernaut and Juggernaut Recon health regen. It's absurd that the juggernaut only gets weaker and weaker as it fights. At some point, you become weaker, slower, and more visible than a normal player.
The Assault juggernaut cannot ADS or refill its minigun ammo, and teammates don't benefit from the juggernaut recons radar.
