I pretty much only play soldier and pyro. It's funny because pyro is the one class that I never worry about running into. 9/10 I kill them, the only time I don't is when they surprise me on my last rocket and I don't have enough time to reload. I generally just shoot one to blow them up in the air then wait for them to come back to get me and finish them off. I can't wait for this update though, should make pyro a lot more fun.
