Marleybone: I can't get past the Radicals!

Hello! So I just started Marleybone, and I am currently on the quest "A Frog in the Foxhouse", and every time I fight the Radicals, they always get me and all of my companions killed. All of my companions are the same level, and basically at the same health. Whenever they hit me, they're always epic hits that pull about 300-400 damage each time, so I'm killed within a few rounds. My armor isn't helping me at all, and none of my companions epics do anything, like I've noticed they don't use their vengeance strike or blade storm of double taps against the radicals.
Does anyone have any suggestions on what I can do?
