I was around earlier today when the Rook blitzkrieg'd its way all over Ur - I must've taken part in about 5-6 different attempts to drive it off. Which got me thinking - why don't we have any cheevoes for beating Rook attacks?
They could be in the same style as other achievements; 'So-and-so has fought and won against the Rook 3/9/18 times, etc.' Considering the new reward system we've got for Rook attacks, it'd be cool if we could track our battles with some new, shiny badges :)
