Poor behavior coming in Outwitters?

[SC-FTW]

I usually say "Good Game" after the match is over. I like the full words.

I personally don't mind when my opponent says GG before it's over.

A few times I didn't die and they were very quiet after that.

Also when they say something like "That wasn't good at all!" (Usually after they've lost) I always comment and give advice etc (even though I'm probably not really qualified to do so ).
