Join Dungeon close to last Boss

We found this helpful glitch that can be used to join dungeon groups that are already formed and have a boss or so down. 

When you Q up as a tank/healer/dps and your group is formed, simply right click the dungeon finder on your mini map. It will then say "enter dungeon" or "leave queue" 

These options should stay in the same spot even when you move your mouse around the screen. Then simply hit enter dungeon and if you do not instantly get teleported into the dungeon then the group is still being formed, and its a fresh run. Simply hit leave Queue, and repeat until you instantly get teleported into an already formed group!

This is extremely helpful for tanks and healers who only need items off bosses at the end of a dungeon, or just for anyone who is just farming valor
