To be honest, I don't see the big deal. I have crafted reusable 48 medkits and adrenals for all of my pvp buddies, and keep them well stocked with the death persisting stims. Compared to Rakata stuff, there's not a whole bunch of difference- their slightly inferior versions still give them the same get of out jail free card or massive burst that biochems can get. In short, just spend a few creds on getting your own lvl 48 reusables, and then you'll be just as "overpowered" as everyone else.
