Maybe rash but whatever:
I find the notion that the GFX team not being able to come up with 10-15 unique, nice hats for a holiday event they new was coming up months ahead to be completely unacceptable. How is it that Unholy Nation is capable of delivering nicer (and more) hats with an average player count of 20? Hire more people if you need to, but I think 4 hats and 1 mount + a bunch of one time use items and fillers to be giant slap to the people who actually took a lot of time out to do well in the event.
Again- loved the event. Was fun hunting pumpkin blobs, ghosts and goblins (maybe could have used more ghosts to keep up with the rising player count), but I don't think it was executed well because of the prize pool.
