I would like to see PvP with it's own zone with it's own rules leaving PvE alone. The few games I have played, developers nerfed classes for PvP because their damage was too high. This made them less effective in PvE as well. It should only be changed for a specific zone.

I would hate to see really good gear coming from PvP events. I hate fighting players, it always amounts to the same thing, being a cheap as possible. If good gear came out of this, it would force me to have to pvp to get the gear.
