This game is simply getting more popular, more options can only be a good thing. Missing a duel/ spar mode (something in a great deal of this games competitors), in my opinion is detrimental. Not only does it fit the Lore of a fantasy themed game (every one duels in the msq people) it would (as many have pointed out) offer something to do on the down time of raids, dungeons, hunts, ect... We are going to Ishgard ladies and gents, a place on knights, where honor and martial skill is paramount. What better place, what better expansion than this to see such a feature?
