I know this is very different from normal GST standards. But why not make it Royale style?

Say 15 teams get accepted. Create a very large battleground. 5 people per team. And it last for about an hour at most. All teams get sent in at once. And basically force people to strategically work together to bring down the 70 other people. There will be no healing. And GST rewards only go to the top 10 teams who make it. Or something Royale style. Would be interesting to see the overwhelming pressure put among players to fight everyone all together. Or maybe that'd be too difficult. I do tend to like to make things very difficult
