The game doesn't seem to do well tracking revives or assists from revives, so people seeking points are already turned off. If they got more points, or more assists, I'm sure the number of medics reviving would increase.
I'll also say, as a support main, that a LOT of people get downed in a terrible place then rage when a medic won't run in to die to rez them. If the medic does, then the person dies after getting rezzed, they still blame the medic. It doesn't help to just have two dead players, so be mindful of how bad of a place you die in when crying about not getting a rez.
