I would like to give all of you my advice for the best Medic setup/loadout/whatever the hell you want to call it.

Okay, so it depends on what you do as Medic, do you mainly heal players, or fight? There is a good loadout for both:

Battle:
Medigun: Since you probably won't be healing, choose any medigun
Weapon: CHOOSE A CRUSADER'S CROSSBOW! THAT IS A VERY POWERFUL WEAPON
Mêlée: DEFINITELY UBERSAW

Healing:
Medigun: Kritzkrieg
Weapon: Maybe a Blutsauger?
Mêlée: The Solemn Vow

Thanks!
