It will also destroy GG capital even worse than it does now,
How will game balance be affected in you go from a guaranteed win that takes 2 minutes to a guaranteed win that takes 80 seconds?
I'm not buying the "pandemonium" argument. The primary effect would be in mirror matches and the primary impact within those mirror matches would be on the player side, not the AI side. It would simply make strategy easier when you have the option of refreshing before it expires - you'll lose a turn on the back end, but you keep your ETA from being exposed too early on accident. That's it.
