Was actually shocked last night when I played, I tend to play BF games almost exclusively as a medic, so I spend most of my time (and often my deaths) running out to revive people rather than charging forward guns blazing.
Yesterday I decided to try an evening of Assault play instead and I can honestly see what everyone is saying about medics not reviving. I never noticed it when I played as a medic but I can literally count on the fingers of one hand the number of times I was revived last night. I always made sure to leave off pressing the space bar to give medics the most time to get to me but 9 times out of 10 it just never happened.
Maybe they can make it so that reviving someone gives you 5000 points or something stupid as an incentive to bother reviving , speaking as a medic player I am shamed that so many medics seem to be using their class as a glorified self healing assaulter rather than a squad medic.
