Grand Arena, hide banners before end of the round

ToLive

My GA always start at 2-4 AM, and my opponents seems have different timezone, so I can wake up in 6:00 with all my defenses cleaned out. But if another player is smart he will wait for my move. And this is a great strategic disadvantage that I should start the attack near 3-4 hours before end of the round. So opponent can calculate an average banners he should take and make the decisions like "Take a risky non full party to attack or bring a safe full squad for less but guaranteed banners".
I think current player banners should be hidden until the end or the round, so opponents can see my actions but not see the results of them.
