I want to start by saying I am not trying to be mean. However your toons have no synergy. Your top 10 toons have 2 scoundrels, 2 empire, 2 FO, 2 Rouge 1, a resistance and Mace (which sucks). to easily complete GW consistantly you need to have at least one very good team (with healing abilities) if not two. Typical teams for your level would be a Phoenix, full resistance, Rogue one or very strong rebel. Instead of spreading yourself like you have been focus on one team and hit all five toons and go to completion. Then focus on your second team ... rinse wash and repeat. Good luck!
