I honestly feel very 2 sided about this.
1.
- I think it would ruing the detective experience
- it would slow down the game
- it would cause many reports and rdms where people don't agree/understand why killing on dna is rdm ( i know we can explain them but it really isn't convenient)
- Asking a traitor why he shot somebody won't get you anywhere as he will just lie, no point in using the dna scanner at all then. You can then say : "well you need to figure out who is lying, its strategy" but if you decide he is lying then it would still be rdm as you can't ever proof if he lying (except in some very rare cases)
2. You could have a perfectly fine reason to kill somebody and then die because of dna.
As it might look like i am way more against i do feel like the pro-argument is really important. In the end i do think the karma punishment does the job and killing on dna should go without any problems.
It should be that if you kill somebody with a valid reason (ex: self defence) that you post this in chat. Then if a detective or anybody with a scanner kills you it would be rdm as they should of checked the chat.(similar to the T traps rule) But of coarse then again the traitors could claim it was a valid kill aswell and it wouldn't go without any problems either.
