I don't think it's a worthwhile change to make, considering Lack's behind schedule on the other changes he's planning on making. Is it really that much trouble to hit "end attacks?" While I agree it is a lame strategy to conquer territories and then wait out the hour so as not to get a card, I still don't think it's worth changing to keep those lame-asses who do that from slowing the game down.
I also think it's lame when people put huge banners under their posts with flashing lights, and crazy graphics. It's like "LOOK AT ME! Pay attention to me! Here! Yes! Me! I'm important!"
