I was thinking - points of the opponent should be hidden during GA. This is because it is a huge factor in determining your strategy when it comes to really close matches. If you opponent goes first and clears the board, but you calculate that on average he use a full team and has no health and protection bonuses, u will try to use a team that could max out those bonuses. Likewise, if your opponent has been fielding full teams and maxing out health and protection bonuses, u would then decide to send in an underdog team to get unused slot points.
This is something i find to be very advantageous to the last minute attacker, as compared to those who attack early in the day. Sure, if you live someplace where GA ends at 11pm, you can wait till the last hour to decide. But if GA resets at 3-5am, then you have to hit earlier and let your opponent plan around your points.
Tldr: Hide points during offense phase of GA.
