goa gold, gates of andaron gold

Now, instead of going to the back area and getting the crystal here, go back across the bridge (towards where you disabled the gates of andaron gold first mine) and attack the group that wanders back and forth from the rock. 

Try to catch them in the middle area and you won’t get either group behind them. Now, time your attack on the left group, then the right. After those two are down, there’s a boss to the left and a group to the right that occasionally wanders towards the boss. 

Take out that group first, and then move onto the boss. When you pull him, be sure to pull back a bit, especially if he’s a caster. The group behind the wall has a tendency to aggro and the healer will just keep refreshing his life and things get hectic and time consuming. 

Once that’s over with, head west and take out that group that’s nestled into the wall there. Then take out the group south of them (towards the crystal area) and disable that mine. 

Now, head to the crystal (sticking very close to the wall), take out the boss, grab it and run back the exact way you came in. A new group will appear, if you can pull them without aggroing the boss then does so, if not, then just run by.
