I really hope you get camped soon.
Griefing is pathetic behaviour, and the argument that 'PvP is on a PvP server' is pretty weak to say the least. World PvP is when you meet someone by chance when you're both questing. Not when you purposely camp a portal waiting for people lower level then you to pop out so you can repeatedly kill them with no effort or risk, especially when you have friends with you already.
And no, don't use the 'it gets people to log their mains!' nonsense. People are on their mains already, trying to level. If you want to fight people the same level as you, go to higher level zones and stop being such a wimp.
