so if you seen one of my posts or found me in-game playing treasure wars, you might know i don’t like rushing strategy, as it stresses me, but, i honestly see it a bit humane if you are playing on solo or duos, and come on, that is why quads was not deleted, because there is people that still like the old strategy, but here is the thing: most of the times nowadays, you end up in teams of 1 agains teams of 3 or similar, so i think the best way to avoid this happening are the next two options:
allow people directly join server: if the round has started, and the problem has appeared (eg: team of 1 vs team of 2 vs team of 4 vs team of 4), new players can directly join the server, now this is a bit hard especially for the player that joined, so i think this one is bad, but not better than the second one
make it so 16 players needed to start and if someone leaves in 1 second before starting it resets: pretty much it, minimun 16 to start, if the 16th player leaves 1 second before starting you will have to wait again until another 16th player joins, as well as bad as the previous one
but this is the only way to resolve the problem
