tf2 is not about skill, it's about getting a good team and not being retarded
False, though on a pub that is generally true.
If you disagree then you've never went pub-stomping with a friend or three (you'll want a good medic) and proceeded to destroy the inevitable stacked teams. Naturally you will be on Team Fail (the one that is otherwise filled with mental defectives and those who haven't switched teams yet). Bring a good medic, soldier, and maybe one or two other good players (a "competitive" sniper and/or a demo are good choices, ideally they can switch classes as needed) and you're set.
Even with the rest of your team being so dumb that they can barely understand the concepts of "stand on point,
stupid" and "keep pushing tiny cart" a small squad like that can destroy the "good team" on a pub.
