I'm not a PK person, and never really was for PVP. I have adapted though. I'm ready to switch channels as soon as I see a suspicious blue dot on my map. I even go into Justice mode sometimes. I understand though. There really isn't much casual play involved. Especially when you basically have GM's killing you with town monsters. It was a slight and temporary annoyance, but this game doesn't need any more of that. I tried to "join in the fun" with my higher alt, but was rejected from party. This game can suffocate you and make you feel weak or slow, quite fast. I still like to go at my own pace, regardless of how much free time I have.
A PvE server seems a bit overkill. I just think something is missing here. It would be nice to opt out of the PvP system, and perhaps take a penalty of some kind for being safe. We can't afk level forever, and to me the whole Justice and Peace thing doesn't feel complete.
