You basically need a headshot with it to get a kill. Considering how exposed you are when using it, it's excessively bad, so much so that you can't even count any kills as anything more than sheer luck of the draw. And that's not to mention HOW INSANELY USELESS that minimap is to aim with, it even ZOOMS OUT to make it additionally harder to even get a hit when the "general area" isn't necessarily even 2m from the target aim.. if anything it should zoom the map in and or AT LEAST give you a zoom-keybinding to change the minimap-zoom.
Currently it is no more than a silly way to pass the time.
