Nexus Blitz Quality of Life Suggestion

This is not the first time it happened, but recently I played a Blitz game and there was the ring of fire event where in the end only one team is left standing. Immediately following this event my team was dead with 30 second re-spawn timers as the walking nexus even took place and we could do nothing but watch the grey screen as our nexus was destroyed. There may be similar cases to mine that happen often, as i said it is not the first time something like that has taken place, therefore i think it would be a nice quality of life improvement to not have an even the minute or so before the walking nexus to ensure both teams have a chance for one last fight to bring down the nexus instead of just being forced to watch it explode due to an event.
