While reviving certainly should matter, I don't think that it's worth as much as a kill. You're essentially just hanging back and waiting for your average sub-1 K/D player to make a mistake, so you can smoke your own teammates to secure a revive.
People that are making the most kills aren't the snipers. It's the highly skilled players that move the game forwards. They don't just click dead bodies. They have to win engagements where the enemy shoots back.
Medics already are the easiest way to farm points, because good medics can combine reviving with killing and get more score than any other class.
