While reactions to something new are likely going to end up being negative just by human tendencies... I feel like this new crit system has more than just that pulling it down. The system adds nothing fun, and doesn't really add more variety and options. My most interesting medical experience while the test was on involved a maddeningly long decline through which I was unable to speak, offer advice, make signs, nothing. I just sat there gasping as life slowly ebbed away, which was terrible, but that wasn't too bad because it was dramatic and created an interesting story. The part that made me upset was after this long struggle, they popped me into a cloner and "ding" I was back in better shape than I was before.
I don't know if this is what you were going for, it seems like it takes a lot away from the fun of the game to create a little extra RP that was sorta there already. The "depth" of the system is bottlenecked by cloning and SR already.
Gameplay-wise, and even RP-wise, it would have been more merciful for the Paramedic to put me out of my misery and just focus on cloning me since the cloning tanks were free.
