Considering the defibrilator that thing got nerfed and it now has a several second long recharge rate (so no more mass respawn). I also don't want to miss it in any BF game as it is an essential thing the medic is about. I guess we don't need to talk about realism here and the full health respawn also might be something to discuss but it isn't that strong in BC2 anymore and most players seem to ignore dead teammates anyway which is a shame but people not giving med- or ammo-packs has always been a problem...
BTW:
I just unlocked the M16A2 assault rifle and it's godly! Seriously it has to be the best weapon in the game and lead me to some 18/3 results and best player badges (and I'm actually always using the smoke grenade launcher because it's so much more badass). It's precise like hell and with its three shot burst the good BF2 times nearly have come back...

I also sort of changed my medic weapon and now pretty much just rely on the SAW. The M60 still is good but it has it's advantage in distance combats only. As I'm no camper unless I'm in flag capture range it just doesn't fit my gameplay though. In close combat the SAW is so much better due to the high fire rate and so you don't die because the assault or engineer enemy simply pumped out more shots than you. With two shot bursts it also is pretty accurate on a distance even without the accuracy increase...
