When I play TTT, it isn't RDM if you kill an afk person after 8 minutes or if you have reason to suspect them. You can push people to their death. You can kill anyone you want, besidest he detective, at any time as long as you have a decent backing, like you saw them walk past an unid'd body.
90% of TTT servers rounds take 8-10 minutes, when they should only take 5-6 minutes.
