I love playing control points, and when we have the third (middle) point captured watch the engies sit back and defend our last point while the other team overwhelms us with ubers, gunslinger sentries, and demo spam. Lord_Iggy and I just finished a fun 2 v all where we saw that, plus pyros sniping with shotguns and three scouts on our 11 man team. While we lost, we fought the Good Fight (TM).
Although the highlight of the night came before, when the two of us were on opposite teams. While he was ubercharging a direct hit soldier, me and my 7 HP escape plan soldier literally ran circles around the ubercharged solder avoiding his shots until the uber wore off, at which time I critical hit Lord_Iggy off the bridge and ran away. Lolz were had by all (well, maybe not all. Definitely by me though).
