I got Lvl. 5 Medical Applicator Lvl. 3 AoE Heal Lvl 3 Nanoweave. Should I focus certing into the GR-22; or should I get C4; or Revive 'nades?
Heard bad things about the revive grenades. On a personal and only observational opinion, they seem way too situational for what they are and cost. If a team goes down, rezzing them all back up is probably just likely to get them put down a 2nd time, or only save one or two people out of five which you could've done just as easily with your maxed med tool. Level 4 AoE healing has my vote, at the very least. That way you get the full regenerative potential out of it. Level 5 just lowers its cooldown.
I have seen one time where revive grenades actually sort of worked. I have also seen a ton of other times when they have just been wasted to get maybe one person up.
