There have been some discussions of removing cloning in the past, namely this one
from 2017... so, its been a while since this has been brought up from what I've seen. My thought is a bit different from this topic, however, I do agree with the ideas Wolf brought up in this one.
My thoughts would be to not entirely remove cloning but allow people to make a preference on the character screen whether they want to be clonable or not (has to already be a clonable species obv.) It would be something you can only change between rounds but allow you to mark yourself as Do Not Clone (DNC) which would show up on a health analyzer. It would also display a message on the cloning console when you tried to clone someone that was DNC (something similar to unclonable species now).
I think this would allow for more RP than just "Oh, defib doesnt work anymore, let's clone em" cloning itself is just a boring deus ex machina of BAM you're now alive again magically. It is a process of course, but its such a bad RP element that adds nothing to the game. It also does not allow for new medical players to actually learn how to play med well. If you all you know is, "darn, the patient died, guess we just clone", you come out worse off as you now aren't learning how to TREAT people.
Needless to say, this suggestion is here to find a middle ground between completely removing cloning as it is, and leaving cloning as it is. It allows players the choice that we sometimes wish we had. Thank you for coming to my TED talk.
