Note that medic shouldn't always take raged FP hits on himself. When there's a berserker with full health, he should take FP hit. Reason? He can be restored back to full health in seconds, and the precious medic's armor should be saved for those occasions when FP is coming after someone who won't be able to survive this hug.
One time I played with some jackass zerk that just charged at FP, raged him with continuous katana primary fire and then tried to flee. Several times. I did my best to heal him, but when he finally died, he was all like 'noob medic doesn't sponge fleshpounds'. Needless to say, next wave I just let the natural selection thing to go on him.
