Again, rev/nexus/crypt are always open for a minimum of 3 days. I thought that was a given. I understand they wanted to open it on Halloween, but Halloween happened to fall on Saturday.
There was even a time when a recent nexus (the one prior to Space Nexus) closed prematurely and then was re-opened for another day.
Trick or treating lasted what felt like forever (and went on past Halloween).
There's a ton of people that don't or can't play Graal every day. Club Crypt is a big event. A day and a half just seems so short. I'm not just speaking for me. I'm speaking for all the casual Graal players who missed out on it.
It's the goat mount all over again.. (which was later re-released however!)
