TorB, a thing you have to understand about mafia is that normally lynch and nk alternate. The latter will always hit a town. The former usually doesnt have that much better odds than random to hit a mafia. If you have one shot that you have to use immediately or lose it, shooting at random has effectively a better chance of hitting a mafia member per death created than the lynch, as the lynch requires a nightkill to have occured before and usually people arent that amazing at hitting mafia with the lynch.
I'm saying this now, because in both etg and the last mafia you used too basically think the same I did (just better) and this time we somehow seem to have fairly different opinions about robs action, and that made me suspicious of you until identified that that seems to be the source of our disagreement.
