The same way every other "super" is balanced. They're not. They're supers. They're supposed to be OP. Know what I do when I hear a Sunbreaker activate? The same thing I do when I hear a Blade Dancer or any other super activate. I run in the opposite direction. I'd be stupid to think I could kill them with a sniper or shotgun most of the time. Ya, you can get lucky and hit them occasionally, but the majority of the time, that super is going to own your ass. Play smart.
