Well I'm thinking what we could have is that either:
1. Since our bodies are more fragile and prone to damage than a Pred's, maybe we get to use it 2 or 3 times.
2. Or we could instead have a special person carry the medkits around and we will need to come to that member to heal. That member, though could only use it once, and if he's killed, we lose our ability to heal.
What do you guys think?
