If I lose I usually ask what I could have done better...I just played RukaNewton and lost because I couldn't figure out how to get rid of his double snipers.
He wouldn't answer any questions except to say "more active." With lots of replays to look at anyway, why are so many "pros" so reticent to help other players?
People are asshats, there's no explanation required to be brutally honest. If people are reluctant to help other players then it just goes to show how enclosed and insecure some people are. I'd seek help and advice from elsewhere.
