This will not help people in different time zones. No matter what, alliances, if they are smart will launch a blitz at the same time and rely on their members to log in at that time. So even with this change, alliances will still set a specific time to blitz and as we all know, its going to be night and day in different parts of the world. With that, this update has no real benefits, only negatives, as stated the main one is the double buy. In a game where we have been trying to help people have better chances in the defensive position, getting rid of the only thing that really gives anyone a chance at coming back in a war is a terrible idea.
