TF2 a great game.
But with HORRIBLE community sometimes.
I know too much TEAMBASED games where people go: Team? What is team?
Either way I been to alot of clan servers and I honest never hade this problem.
Well mostly since the admins there find me a too fun of a goofball.
The only problems with some "clan" servers are the following:
Admins who screw around with the progress.
Premium powers that make every donator a god.
General TF2 problems:
Medics: You play one... no one protects you and you get sweared at for not healing. Ally medics wont heal you but the heavies then swear at you for not protecting them with your 1 hp or they only go battle medic. (wich is fine)
People who spam trade.
People who spam mics.
People who are just blatently annoying.
Being the best of the server but always on the losing team. (YES I HAVE THIS ALOT! Some noobs are so bad in spy aware.. I run around as a disguised scout so I walk slow.. and even then they do not spy check me...)
General problems in Team based games:
Lone wolves who do not care about their team
Lone wolves who swear at you for not helping em.
People who do not understand the OBJECTIVE of the game and go for pure kills.
People who fall for "Easy" kill baits.
People who refuse to communicate but then talk when you failed to them. (got the same problem. But I never have enough time to warn em or give a hint of don't do that, I don't call em stupid)
Leeroy people.
And last but not least... AFKERS!
