How to tell if your team will win in TF2

Meh, the thing I don't like about competitive play is its lack of making use of all the classes. Competitive teams are usually 6 players, 2 soldiers, 2 scouts, 1 demoman, 1 medic, and occasionally a sniper. Engies, spies, pyros, and heavies are pretty much completely written off.

Also, do not doubt the spy rush. The other team gets so confused when the other team disapears and their team double.
