If we get a week or so warning, we should have an end of beta event for all three realms. Maybe a 3-way hug-fest in the frontiers with every body online followed by a massive slaughter!
Some major event for the whole last week of beta would be awesome. DF open to all with some GM's playing special toons that either try to hide and we find or that are OP and first realm to kill one gets put in the record book.
Frontiers have something happening that gets everyone involved both high and low lvl.
