I have always enjoyed PvP, but only when I want to PvP. I miss DAoCs separate zones.. each faction had its own leveling zone.. you could go there to PvP..but it was not easy.. took a lot of time to get there. Most the PvP happened in the BGs, and The Frontier ( RvR Zone ) IF you enter that zone.. you are PvP flagged, the quest rewards were better.. the loot was better.. but the risk was high. But your PvE zones were different areas of the map for each realm.

CRZ could implement some kind of restriction on PvP servers so that CRZ had level limits. Other than that, you just have to find a work around. Like transferring one toon, that you don't use much, to a PvE realm on that cluster ( can you do that ? ) And inviting your other toons to that zone?
