We tried backing our tanks into a corner (where you first start) one took queen and other took the other big ant and kept all the DD in there as well and the White Mage. We then tried luring the ants into that area so that the Black Mage was waiting to sleep the minions as they almost came in funneling them and keeping sleep on them also giving room for the DD to use area attacks. We managed pretty good but we lost about half way through as I was the only Black Mage and there were just too many ants I think if we had another Black Mage and White Mage it could work.
