yay I get to respond again so soon, but i still like talking about the classes
2.medics will still fight but simply have a healing mind set, same with engineer and demolitions they can still fight and kill people but they would try to repair and make thing or blow things up more then straight up killing because of that mind set. Did they ever say you cant get a license to heal people, repair vehicles or get explosive charges or that you cant do any of those things? You don't need a label like medic engineer or demolitions for you to make that your main thing. while it might help other people understand what you mainly do, you colud always just tell them. they way they have it set up makes it seem like a more realistic rpg. you start out at a low place with little specialization then as you go you specialize yourself in any way you want to instead of starting out specialized.
