As I've been playing almost nothing medic since launch, it's just difficult to do. Again it's another problem with the giant huge open maps. You are often picked off trying to get to someone, or it's just not possible to get to anyone in time to rez them. Unless you spawn and stick to your squad mates, the game can be really tough for any team play or squad mechanics to work. I can imagine folks who like to play engineers fixing vehicles have similar problems as the vehicles just zoom past.
They fixed visibility and its friggin clear as day when a person wants a rez, but so many players don't even try, you just see them stomping past your corpse as you scream out to them, it's so annoying as I can't blame the game for that, but players are just shit at helping out others.
I was on the roof with a bunch of guys, I was healing them left and right, rezzing them over and over, then I got picked off, they all just left me to die. Fuck em.
Nah, they still try and you can tell when they are trying to revive you when the bug kicks in. Most people just are assholes and seem to just ignore you.
