as someone else mentioned, the great thing about pvp in this game, will be that anyone can play any class/job. it doesn't take a lifetime to level a new one, or create special setups just for pvp. so in theory, everyone should have an equal chance at being "OP" and being the underdog.

I hate to get into this part of it, but it's difficult for any game to exclude the rock,paper,scissors aspect of 1v1 pvp. there's always some class that will be great at beating whatever your playing. what I'm looking forward to are the same job duels, and supporting a party in open/arena combat.
