Reusable stim/med = permanent benefit right?
How about you craft a chest piece, mod, barrel, blaster and equip it; it will persist through death and 2 hours later it vanishes...
Sounds like your logic on nerfing biochem is somewhat flawed.
Except that only biochems can use that reuseable stim. Everybody else is stuck with a chest piece, mod, barrel, blaster, etc. that poofs 2 hours later. (or in the case of adrenals, 3 minutes)
