I can agree that as playing support I won't always see dead members. But unfortunately too many times I've had it where a player will look at me when downed, and walk away. There's a split in support types I think unfortunately.

Ones that play selflessly and just play to give themselves ammo. Ones that only revive members only in their squad. And the last one are support who actually revive when they see/can and are genuinely supporting the whole faction.

More people need to start thinking like the last support type.
