The only real issue I had with the event was getting it confused with all of the other events going around at the same time. It felt awkward that this event would spawn on top of other events that were going on at the same time – I didn’t realize the mordrem event circles were red instead of orange and kept getting them mixed up and doing things instead that weren’t part of the actual mordrem event. It took whispering an anet dev who happened to be at the same event as I was and him explaining the color difference before I figured out what I was doing wrong.
Then again, I am apparently a horribly oblivious person when it comes to things like that.
