Guild Wars 2

Why i can’t start Dragon’s stand event
It always tell me “the Mordremoth was win and sent me to the friendly outpost”
when i come back dragon’s stand WP , everyone was gone

This map has a timer and when it reaches zero, map resets. I believe its 2 hours, so if you want to join full map, start looking in LFG when new maps start. I think you can check the reset times on the wiki.

Here’s an excellent timer for you.
