yep, against griefers... I read the guide several times and doesn't look the case at all, but yeah.. fully armoured weapon patrolling a system looking for griefers, and waiting.. waiting.. to kill someone.
I guess we all have our limits, I'm still here in my multipurpose ship, playing in open, barely survived some pvp and wining others.
For me PVP doesn't mean -get the most heavily armoured ship in the game and get ready for combat- it means player vs player, and hey, if I die in my ship that is fine. I don't have to kill the other ship if it's repairing and ammo cost more than my rebuy I'd say I didn't lose.
PvP means also defending and dodging, the guide only covers -kill in a rush kind of build and run like no tomorrow- which IMO is incomplete for a PvP approach, but then again, just an opinion.
Adding: pirating is PvP also, this guide doesn't cover anything but killing, so it should be renamed to professional PvP or a more suitable title.
