Playing dweller today, i was consistantly killing people travelling the sewer. When I asked why they didnt just shoot me first, their reply was it would be RDM. Since Sewerdwellers are allowed to RDM in the sewer, their should be at least a rule allowing people to shoot at them if they are spotted in the sewer. Otherwise, it seems kinda like an OP role to have that can easily be exploited by someone trolling other players.
