Soldier joined mid-mission because two people left. Scout timed out really early on, and the other guy probably ragequit as a result.

Forget Demo; what about the Soldier?

I dunno. I guess a competent Engie can dish out a ton of damage (if he actually Wrangles stuff, instead of wrenching the sentry all the time). Maybe because the Engies I usually played with weren't that good, but I didn't usually have much problems dishing out comparable, if not more, damage as a battle class.

And Engie gets a lot of damage first couple of waves. It's the second half of the mission where he should be left in the dust by competent damage classes.

I was going more for "OMG PYRO IS SOOPER HARD CLAS ONY XPRT CAN PLAI KICK 0-TOUR"

Durp. Tours =/= skill.
Also, why 5-tour Soldier's damage barely exists, and why no one from the team managed to best Engie in terms of damage? (If a battle class got less damage than Engie then it either means Engie is playing aggressively, they're low on upgrades, or just plain aren't good enough.)
