A defense of the comp scene is always appreciated but people forget that most of the casual tf2 playerbase is filled with people who don't even "play" the game

as you can discern from the above graph (even if it is a bit outdated) the absolute majority of tf2 players are found in gamemodes not included in the base game (only 25% actually play the game & even among them most are found in 24/7 2fort as seen by the ctf portion), and this is not surprising considering how tf2 was marketed by valve ("Hat themed simulator")
most players treat tf2 as a free version of gmod more than a multiplayer first person shooter and as such they bemoan the existence of competitive gaming in general, let alone competitive tf2.
Tangentially, this is also why any discussion of game balance is also completely useless as how they view game balance is fundamentally different to how we or even the players who play pub tf2 view game balance.
hope the video comes out great however and it leads to changed minds
