Notification for being attacked in grand arena

Agreed, I think the GAC live matches are the most exciting thing within the game right now.
In my last round my oponent pulled of a nailbiting finish and managed to beat the last team he needed to overtake me by a couple of banners with literally 30seconds left on the timer for the round. I sat there wishing I could actually watch the battles live, seeing which moves they were making. Maybe even with a non-text live commenting mechanic as they have in Marvel Snap?
