1vs1 question?

I thought factions was going to have 1vs1 fights I know this is a dumb question but how do i get to them?

Go to your guild hall and start a scrimmage match. Have one other person enter. Bash his/her brains all over the guild hall that your kind leader just finished scrubbing. Rinse. Repeat.

Go into your guildhall with the person you want to duel with, enter guild battle, select "scrimmage". the other guy does the same thing, and joins the scrimmage.
then it is a normal GvG battle, but only you and him.

There was a "Gladiator Arena" planned, which was 1v1 I believe, but the idea was scrapped before the release.

So this makes a 1v1 round?

well, just leave all he NPC's in a place where they wont attack. go into some out of the way place, and have at it
