Only the bad medics. Don't worry, there are a few medics who are actually good. Just like there are only a few Operatives who will be good.

Yeah, but we all know you're going to be following Wraith around and since it would be silly to expect Wraith near his team it would be silly to expect you near the team as well. :hehe:
If it was me, I would revive my teammates as often as possible. And if my revive had to cooldown, I would defend them until the cooldown is over like a true war hero :gun:
Then perhaps you would make a good medic.
It's the same situation with the way people view "snipers" and "Operatives" in that it isn't the class that is the problem, it's the people playing the class for such and such a reason. A good Medic, Sniper, or Op is a great asset, just like a bad Medic, Sniper, or Op is a really frustrating player to have around.
