The pvp pros and cons are always an ongoing back and forth on this forums so i will not comment about that. The post content tho is just a player blaming the game for not having the kownledge of desert pvp. The game encouraged (less now but still) the pvp in the desert and thats why it has special rules. Everyone who flags on the desert will go to the jail if killed,the game treats you as an outlaw regardless of karma. So now you know why you got sent to jail.
