Would someone mind giving me a quick run-down of the different combat medic abilities and tools, an how they work? The wikis I've read are either out-of-date, inaccurate to begin with, or don't tell me what I want to know. For example, the kind of explanation I'm looking for is: Nano-Emitter - Place on ground to heal nearby allies. Advanced Shield Capacitor - Reduces shield recharge delay & increases shield recharge rate. Specifically, what's the difference between the Nano-Regen Device & Symbiotic Healing, if any?
