There's plenty of other PvP games out there with a focus on PvP. You're never going to find the best PvP in a PvE focused game. I would rather see no PvP at all in FFXIV and allow focus on good PvE instead of trying to mix the two, then go play a PvP game when I want some PvP.

Any PvP that is introduced should be confined to arenas where battle is on even grounds. That's really the only scenario where PvP is a sport and not just a matter of fight when you have the upper hand or run away when you don't.

Edit: on a side note, I do like the PvP idea mentioned, but not for FFXIV.
