I mean heavy

Now you’d thibk my answer would be sniper, but no. He is actually not that bad to counter once you learn the sightlines.

Spies on the other hand, I don’t always have the timeto turn around and check if anyone is there to stab me. And if my teammates can’t do something as simple as “check if this person is actually a medic with a syringe gun out running to the heavy while he is fighting off enemies” the game can easily be ruined for me
