From what I can tell, I see no problem with their attempted gimic, if we filed a complaint on every antag when they fail on their gimic no one will try anything new. Lets face it, they tried something and coordinated to do it, thats more than what I expect from antag teams from what I usually experience. However, shooting up the merc for killing the HoS and the return for the body They surrendered in the first place makes no sense whatsoever and I feel it should be looked at.
Last thing, if someone could notify the people of the merc team about this complaint that would be appreciated.
