Medic power shift - nerf grenade, buff shotgun.

Medic grenades are currently a bit ridiculous. Their damage stacks so throwing multiple at the ground and wiggling around in them is an easy and effortless way for medics to solo Scrakes and Fleshpounds. Don't have any grenades left because you just used them to kill 2-3 Scrakes you say? Run around with your super medic speed until you find an ammo crate!

I propose nerfing the medic grenade so that it no longer has stacking damage. Two grenades in the same spot will deal the same damage as one grenade. Give a slight damage buff to the medic's shotgun to compensate.

Thoughts?
