PVP

I waited three hours for this boss, when i am trying to kill the boss, somebody else come in this system, becource i am in low sec, low sec is free to kill the player. I have no option, i went back to station to change ship. Different ship has defferent function, if i want to fight with player, i need another ship. Not very long after i went back to staion, the other player left this system, when i went back to the boss. The boss is dead, only wreck is there, sad.
