I'm fine with combat medics (Comedics?) but they better prioritize -
1) Healing than fighting when the team needs some serious healing rather than trying to shoot a clot unless said clot is interfering with your healing duties.
2) Taking a hit for the team when a raging FP/SC comes in because you have better armor than the rest of the team.
And they should learn to preserve their armor and not tank unnecessarily. Yes, I'm impressed you can take down a FP and SC with a LAR. No, you make yourself look like an idiot when you have to tank them (and waste precious armor points) while reloading your LAR.
Oh and their loadouts. If you want to use a flamethrower go as a firebug. Not a medic. M32? Fine by me if you're planning to use it on someone who is trapped by clots/crawlers/stalkers/gorefasts (assuming he is still alive by then). Just don't create a smokescreen for the ZEDS when the demo is blasting the FP to kingdom come.
