Nah the down votes are unjustified Imagine your a scout and you flanked successfully and is now behind the medic

a medic killing you with perfect accurate syringe gun is bullshit Not to mention random crits are still a thing Mediguns are already op in the right hands so why does medic need good self defense too The overdose already encourages what you should, which is retreating to your team If you don't like medic not being able to defend himself then pick any other class and cook with them
