How about you stop and think about it like this radio.
Fibroblast grants immunity from stat loss, from all sources, forever.
Brainbox grants Immunity from stat loss from dying once, needs a med roll probably, and then has to have the biogel replaced.
I think 4 tokens for the backpack system and 2 tokens to repace the biogel after each use is perfectly reasonable.
note I said after each use, not mandatory upkeep... thats just a terrible idea.
The fibroblast doesn't give immunity against all stat loss sources, unless pw is willing to have us rebalance the thing, which would be the first I hear about it (and is unprecedented, balancing an old pw made item in order to help justify something new).
Most importantly though, you shouldn't be directly appealing to me here, I'm just presenting the council decision on the matter, which doesn't necessarily line up with my own opinions or with what I voted on. I can always collect opinions and quote them in the council pm's or put a link up, but it's not like convincing me will just change the council decision. I'm a spokesperson, I'm not the whole of the council.
Fine, all physical sources of stat loss.
space magic as always is an exception.
as fir appealing directtly to you...
you're the face of the council, who else am I gonna target my complaints at.
