It's possible, PGL was able to do great in that fight before and MNK is much better DD than PGL. If you are new to the fight you probably just have to get more practice because of how hate bounces around while you are trying to burn them down. Try spacing out your Weaponskills a little so you can be sure they are facing a certain way or throwing a Taunt to force them to face in your direction and make it easier for you to combo.
