1. There was not PVP in 1.0
2. PVP is limited to areas in the Wolfs Den. How good it will be is debatable. FFXI had PVP also but it was meh at best and noone used it after a while.
3. There will be no open wold PVP.
4. If you are a PVP junkie I would not be surpised if you are quit dissappointed.
5. This of course coming from someone who seems PVP as something among friends to test out skills and nothing more in general.
