The Hamer and attack aren't really the problem with sunbreakers, it's the massive increase to armor that comes with it. The only counter to it now is to run away but that's futile cause it's a range super. They need to decrease to aromor buff from ~300hp down to about 240 to 260 hp. That would allow this super to be countered by other supers, high damage sniper head shots, shotguns plus melee, or lots of gun fire.
