Imho, flamie is the newb cannon of TF2. Sasha comes in a close second.
"who touched SASHA!?!"
excuse me ? Sasha is not a n00b gun, how dare you!
It seems to get harder and harder to keep your machines alive. Everybody knows where to expect them now and kills them off pretty quickly. It seems like moving them fairly often is the best way stay effective. Its hard to rebuild on fast paced maps. It seem like you barely have time to rebuild before the other team is already working on your last CP.
That reminds me. I need to buy their new CD.
