I was discussing the Rook attacks with Kristen Marie (when I replied to Pinky Death's status update) and the term 'clinical' came up with regards to the current state of Rook attack affairs. During the height of the Rook attacks, when I was one of the major coordinators for defense, we used to have after-attack revelries of one sort or another, but this is no longer the status quo.
I believe some variation in Rook attacks is long overdue. A couple of ideas off the top of my head was a) occasionally have a stronger Rook attack -- with the Rook being more difficult to stun and drive away, and b) having multiple waves come in.
I am pretty sure there are a lot of other ideas that can be implemented, but the important thing is to remove the clinical nature of the current Rook attacks and bring back the excitement of participating in one.
