There is no such thing as good PvP.

PvP goes like this:

Player A is higher level and stronger than Player B; Player A wins.

Player B calls a friend, Player C, who is higher level and stronger than Player A; Player C wins.

Player A calls a friend, Player D, who is higher level and stronger than Player C; Player D wins.

Rinse, lather, repeat.

YAWN

Frankly, I'd rather see the devs focus on something more worthwhile and entertaining than adding in such a ridiculous thing. But I also know, for some odd reason, some people actually like this kind of gameplay so I hope eventually some sort of PvP ends up in game for them. I have a feeling you can look to XI for the kind of PvP you can expect here though. It may not be what you think.
