Sorry to say this dude, but the aggressiveness of you post kinda prompted me to be point blank and blunt (Kinda kidding btw, but kinda not at the same time
)
A team consisting of 1 Sharp and 5 Commandos/Support just means the team can't win without using over powered weapons, ergo... the players are crap
True professionals use things that make the game challengning for them, which is why noone cool uses the P90's, LMG's and auto snipes in Counter Strike or Call Of Duty.
The Medic, Zerker, FIREbug and Demoman all require the use of a brain to play effectively, so to say players are bad because they use them is like saying anyone who tries to play guitar with his fingers instead of a plectrum is an idiot. Yes it may be harder but the rewards for actually achieving it are far greater.
Love your work and contributions to the forum Anth, btw, but I can't stand it when people rip on the firebug, just because its not an instifrag class like everything else is. I personally applaud anyone who experiments with low powered weapons over just going for the easy option all the time.
