Heroes which must be changed:
Darthmaul: Regerneration is too fast, maybe heal by 5 instead of 10. Leave the knife damage alone.
Fartman: The grenade does 10 damage and stops, either it's a glitch and should keep doing damage (which it should becuase it's a poison smoke grenade) or the damage should be upped.
Spiderman: Add a web limit?
Exodus: He's pretty cheap, he should be removed.
Demoman: Might be better if he had 5 prox. mines. Doesn't NEED to be done.
Scorpion: He should have a maximum of 5 shots, right now it's unlimited and can be cheap.
