Bad idea. Sniper with 150-200 FA would be unkillable unless you deliver a instakill. Thumbs down.
Wrong. However, a combination of Medic and Sniper would be harder to kill than before if he has enough time (And APs) to perform a FA in the middle of the battle. And even if this is the case, this also applies to other builds (I know - instakills are still quite a problem, and I'm for their removal). Still, the longer the fight is, the better it is. And finally, there would be a useful medic class
