Why does this game reward negative behaviour?

[Dwork the Orc]

I love the idea of being able to switch off PvP.

Currently I hate it - mainly because of the junior backstabbers. I'm can see I'm not alone.
It is especially annoying of a junior archer hits you with a flame arrow and (for some reason) that doesn't count as an attack, 'cos when I target the troll it tells me they're too low. Sigh.

BUT - I'd love to be able to dabble. I'd suggest settings like: PvP to death; PvP to red; PvP to yellow; no PvP
You never know, I might come to like it!
