not a bad setup , but u don't relaly need both bernice and leanne at the same time in general , so u can switch bernice for now (leanne after u level bernice up) and get more duelists in there. I'd suggest , u use lyla. She is 1 of the highest dps duelists avaible to us atm. She is still a good duelist. Actually , i'd leave julien out as well , unless u specifically need a 2nd soldier for said map , and i'd place sophie in , since she's an awsome lightning rod (btw , u can use her for Imortal beast after u leve her up and your healers a bit) , and u have to learn how to use her eventually.

Other then that , looks like a pretty decent lineup
