Time for some more mathspeak.
Out of the [supposedly 9] town players, [supposedly] 5 of them (light infantry) get fortifications which can block a nightkill. We also learn that Orange had some kind of role which [supposedly] could evade nightkills. There is just 1 medic who can just choose 1 target each night. Are you suggesting that the neurotoxin action would only work for the medic, who could do so much limited saving, and not for the broader nightkill stoppers which [supposedly] comprise most of the town team?
