Basically just pull one side then the other. Dont let the elements get to the Queen or AE goes off. Pull one side kill the 3 princess, burn 2 of them down then clean up the trash. Have 3rd just tanked 1 cleric / warrior works fine. Have your CC(Crowed Control ) team Ranger snare + Bard HighSun to keep mobs away from Queen, can stick a few others here to help kill them.
Repeat on the other side but once the last princess is below 15 % pull it over near the queen clear everything up start rotation on your MA finish off princess. Then Queen.
its been a long time since I did queen but that was the basic strat we used for both kiing/queen. Queens adds just seemed a little more complicated to control then the King
