Thoughts on energy refresh rate. Without using refreshes, we have 8 battles to do per day. Right now, this is frustrating because the mode is new and shiny, and I want to play it. However, months from now, I think this will be fine.
Bold proposition, get rid of energy and make the stamina cost per battle much higher. For this hypothetical, let's say stamina is reduced to 0% after a battle, and it takes 24 hours to recharge 100%. This way, if you have a very deep roster and want to play, you can go in and use your 16+ GAC teams. With the refresh rates as they are now, I have little incentive to use a variety of teams besides fun.
Maybe this won't be an issue in hard mode. Just throwing some more initial impressions on the pile :)
