This is an extremely frustrating situation.

30 mins in a que to do Stone Vigil as a DD while levelling my alt character.
Finally get a healer to join just waiting on a tank.
Doing a FATE and call my chocobo.
Que gets cancelled. No warning until its too late .. Waste of 30 mins
This isn't the first time I have mistakenly done this.

This really needs to be fixed in some way.
Simply a confirmation box when using Gysahl greens when qued for duty, or the inability to use Gysahl greens while qued in for duty would be an improvement.

Ultimately Chocobos should be available while waiting in a que without interruption.
