Since you want to know so much about pvp, heres what we have been told, yes we have been told before, many times actually, about their plans.

1. Pvp "area" / "region" / etc. a bit like making mor dhona into a contested area where people fight between eachothers. You will be able to party up with people, though, free companies mainly come into the picture here, seeing as a free company can summon ifrit and the other summons in this zone.

2. Colloseum, little info is known, but its coming.

The chance of a duel system and instances coming is of course there, but they havent said anything on the subject yet, and they wont do either, seeing as pvp wont even be there at release, but in later patch or expansion.


Also, just so it is said, no, world pvp wont happen.
