Revenge Kill [RK]: Attempt to physically harm a player who killed you before for the same reason - killing you. Some people think that Revenge Kill is only when you actually kill the person, but it is also a physical harm. This is simple - you are going to kill your killer, for revenge. You can’t do that, because of a simple rule - when you “die” (critically injured, unless it’s a Player Kill), you lose 30 minutes of memory. So you can’t remember who killed you.
I agree this is realistic but we are just living in game and personlly i like to revenge who messed with me and i think not only me everyone will like to revenge others in game. This rule will decrease or reduce part of players fun
