Remember the old Aranna map that had animated rooks flying over the unimagined territory? [here]
I thought it would be a neat idea if any street that had a rook attack in progress would have these animated rooks or be highlighted in black.
This would help to confirm whether it was a genuine attack or a rook roll and help alert more people who might not have global or the rook attack group chat open. Most people who don't stumble upon a rook attack would open the map to teleport to the street so they would see it first.
Not to mention, I think having some kind of animated element on the map was cool.
