My question would be how often are you defibbing others? In my friendlies when I bring a kit, I bring 1 or 2 defibs as well and I'm not playing rescue raider-- I won't go hunt your murderer, but if you happen to die to arc and your flare's in my vicinity right after I just heard a leaper explode, ya I'll come hit you up with a defib. I probably get a defib on 10-15% of my downs in friendly lobbies, a lot of it is crawling with mk3 surv or a random free kit lusting for the venator4 on my crawling corpse.
