Why is griefing fun?

[Watto44]

The mere fact that it's possible to gank does not make it acceptable in any way, shape or form.

Gankers ruined PvP servers. Plain and simple.

I absolutely have to disagree on both points.

1) When you roll on a PvP server (assuming you know the difference between the server rulesets) you make a tacit agreement that you're ok with being ganked. You know exactly what you're getting into, and it's the reason you rolled on a PvP server.

2) Gankers are PvP servers. That's the one differnce between the two server types, and to say that gankers ruined PvP servers is like saying roleplayers ruined RP servers.

What the numbnuts in the OP is doing though is circumventing the PvE ruleset to grief someone. That's not cool, but there's a difference between that and ganking someone.
