I agree.
The doctors and detectives should know how to protect and inspect. Vigilantes, as usual, I'd recommend holding off on night one shots unless you have strong evidence that someone is scum.
I would also try and find one another but if you're unsure or don't want to reveal your role don't risk it! Its not worth it just hope you all don't try the same person tonight! Doctors protect those who you think are vulnerable, don't protect me as I am unimportant. Go for someone who you feel needs it!
