I'll try more to help them out. It's not as easy when you don't have a mic though (I suppose I should get one...) - many people don't pay attention to text messages. Heheh - the new-player engies are most of what I was talking about. They can cost you a game sometimes...
I came across some cheaters today. We were in dustbowl, in the map that has the first capture point in a barn/house thing right next to gulley. We had about two minutes left to defend the last capture point and were doing quite well (well placed sentries, camping heavies, etc) - when an uber medic/demoman team showed up. We had plenty of uber medic-soldier/demoman teams show up before and we always fought them off, with maybe one less turret.
This time however, the demoman used a mine to hop over the gap between the building and the point, landed on the point, and just as his uber starts to fade - BAM! - all of just our team has a lag attack. It didn't behave like a normal lag attack either - we were frozen in place for 5 or so seconds rather than moving very choppy-like. When we came to, they had already captured the point. I think it also happened in the match before as well.
I really hope this sort of thing doesn't become wide-spread. It could really take some fun out of the game.
