Pump panda this past summer was basically private walkon style play no big game.
Talk at that event was to do a 2.5 day event starting with Friday night games, and then an attack/defend (Castle) and a big flag game (Previous pandas) Saturday and Sunday.
Running 2 Castles a year as long as they have, it's been getting a little stale. Fort Worr might just be a plan to liven it up a little. I know getting in is HARD.
