Yeah, I spent the whole game thinking I was gonna be randomly picked off. And the Godfathers come back as townies thing kept me from revealing myself until the end of day 4 I believe, when both Godfathers died. This is because up to that point, everyone I investigated came back townie so any of them could have been the godfather. Reveal myself to the godfather and I'd be dead the next day.
It may seem unbalanced from your perspective, but after actually being the cop and being frustrated at my complete inability to affect the game early on, I would disagree. Like I said before, I really only helped kill 1 person. And using my own intuition I almost screwed up one of Bill/Ty's great votes. (KN vs. IceCold).
