I understand the purpose of it. I still don't have to like it. As I said, it's my opinion. In the case of the "suicide bomber" role you presented, they are no more than a wolf. Same really with the Fool except the wolves lose too. I just don't like it. It's not fun.
Because everyone loses. What did dimmerwit specifically do to win this game? I'm not trying to diminish the win, like Ben, but making the town hesitant to use the tools given to it to eliminate the wolves (lynching) is not fun. Town gets limited kill roles and sometimes none. Taking away the only consistent one, to me, is not fun.
I'm not saying it's unfair. I think in terms of fairness, it is. It's just not fun.
I don't know about the rest of you, but the most fun games I have played have been the balls to the wall everyone blow your loads type games. Not the passive, let's mentally think about every nuance and scenario type games.
Just my opinion. Not asking for a change or anything. Just voicing an opinion. Sometimes these conversations lead to new exciting roles being added, or people stepping up to run their own versions of the game.
