I'm aware that the developers are still ironing out a lot of minor things and probably trying to tune up patch 2.1. However, I wasn't feeling that this event held a lot of significance beyond making the 3 main cities look cooler. A simple (and imo drab) blanket-ghost costume with 2 faces, a couple of different color pumpkin heads, a couple of meager food enhancement items, a short quest chain and 1 (count it, 1) achievement. In the way of things to do to make it "feel" like an event, I felt it's rather anti-climatic. All in all, I'm giving this a chance to see if things will improve.
