I will only teabag under one scenario. An enemy player spots you from mid/long range and proceeds to either shotgun blink towards you or run and attempt a shottie slide. Seriously, people, it's called a primary. Try it sometime, it doesn't bite.
I'm so pleased shotguns are getting nerfed again (I.e., shot package and range finder). When your first instinct when stumbling into an engagement at mid/long range is "shotgun!" you know something is wrong.
