GAC Should Not Have "Timers" That Expire
This has happened to me MULTIPLE times.
I started a battle against QA with Sith Trio. Lost Traya early, but it was still recoverable. I was able to annihilate MQG (the others were stealthed), and then my wife called me to do something I could not avoid. There was 3 mins on the clock still. What i did took no more than 5 total minutes. So 2 minutes over. I come back to the game, I lost (obviously) but then a big pop up said something along the lines of "Your Grand Arena Timer has expired". My kill was erased, my point erased, and an attempt was counted.
This has happened to me several times, and has in fact cost me matches because of the banners. Win or lose, having that battle stay on that screen does not affect anything and shouldnt erase your progress. Its not like you are preventing an action on the other player. I was at the "Submit/Forfeit" screen, my attack should have counted.
