While I do understand the game gives us a "one min. remaining" notification, may we perhaps get a visual indicator when OT is about to start? Maybe the crystal could blink or turn orange slowly has it gets closer to zero or even just another reminder at 30 seconds? The OT starting catches a lot of players off guard and into a instant lost because no one is inside the crystal bounds cause they are fighting off 1-5 enemies at once, kiting corners, etc. requiring all their attention, which is understandable.
But even after all that the team can still insta-lose because the player wasn't inside the bounds at zero seconds WHICH I UNDERSTAND, the problem is the lack of a second indicator/countdown to the end of a game or the start of OT.

Yes I understand that you could just glance up but when you're fighting a group and every skill you use could spell doom or victory, you don't have the luxury to look up sometimes lol and an audio or a on screen cue would really help!

Please Yoshida-san?
