Greetings
Recently while I was doing Dragon’s Stand completion (on a inactive instance) I found a glitch that allowed players to bypass the barbed gates and get to Dragon’s Domain.
The glitch is located between the Central Barbed Gate and the Southern Barbed Gate. From the Central Advance Camp Waypoint head down the southest canyon but stay above on the southern ledges. Walk all the way to the last updraft which you can use to get onto the small cliffs on your right side (on which you can also climb as well by heading farther southeast). From there jump on the large vines below you and walk to its end. On your left side below you will see some bushes. Jump into the bushes and you enter the glitch zone which allows you to bypass the barbed gates and reach Dragon’s Domain.
