And as of the next round, BLU had zero defense, we had an engi from RED trolling through our base, and a medic/heavy combo marching through with impunity, plus a couple soldiers ambling through at will, and a pyro blazing by intermittently.
Our defense consisted of a part-time engi (he gave up and quit I think), a demo, a pyro, and myself. I shifted from soldier to demo to help, but then the other demo and pyro shifted to offense. So essentially I had myself alone against RED inside our base.
I quit when their capper walked right by three other BLU guys (I was watching dead at the moment), and they didn't even touch him.
