As much as I miss the old FH maps and that old character the game had, I'm going to approach this from a different perspective.
I do believe that offering the maps up for download or reintroducing a few would be a great idea, but I feel an official event would just be a bit too much. Celebrating the past is appropriate to a certain point—in Feralheart's case, I feel focusing on the future is the better decision at the moment. As much as I would love to relive the memories I made running through the old maps, I want to be seeing new content and community events. Focusing too much on the past can hurt a community sometimes, and I personally believe it would do more harm than good here, despite having good intentions.
