Unfortunately I was being hit so fast by the attacks I couldn't really say which part I was getting caught in. It was very confusing. I will definitely need to watch the video a few times to see what kind of pattern there is and where I need to place myself. The player they told me to follow was running so many circles that each time I attacked I lost sight on him.

Thanks all for the tips. Like I said, I want to do the trials but they are kicking my butt a bit. Just some more research will help I'm sure. At least I hope so.
