PvP is always fun though there will always be a audience that appeals to PvP in a mmorpg, I think SE should throw that audience a bone.
The problem with PvP is that, when you "throw the PvP crowd a bone", unless implemented very, very carefully, is like slapping the EvP crowd in the face.[i]
LIES, I say..Lies and propaganda lol. Anyway, throwing the PvP crowd a bone is what I think is good business...long as it doesn't hinder the PvE players in anyway. And btw, PvE players made this game successful, not PvP players. So the lack of the latter won't stop momentum in the slightest of whats being accomplished here. PvP players didn't make FFXI what it is today, but im not saying not throw them a bone but its far from imperative.
I think arenas and the like are favorable, places where PvP can be excercised and played with. What pretty much you don't want to do, which is a no brainer, is have any sense of "World PvP".
This isn't WoW, and comparing it too is ludacris. I think IMHO, FFXI's difficulty whether quests, leveling, skilling, and farming makes Open End PvP highly undesirable. Whereas, it excels in WoW due large impart over how easily you can accomplish tasks, also relative time you can do it, and it being a game where you're quite capable of soloing till top level (with good time).
All in all, Im for adding something like maybe "Dueling System", Arenas, or what not that maybe people could even spectate or even bet on...even tournaments maybe even cool. Long as the PvE aspect of the game isn't hindered in anyway, no way you can lose...only gain from giving something to stimulate and entirely different fan base by being innovative and creative. Like I said, good business...I'd think anyway.
