Except Sword is mostly just about the best location of 10 players in the very beginning. Most times this map creates huge gaps cause you lack one or two players on one side then game is done. It's way worse. The size of the map does not prevent players to cluster.
I don't know what you call perfectly fine then, but you should just imagine some players like to play games more clustered and not 10 times a 1vs1 on a huge map. They precisely choose to play something else than 1vs1 where it's not just about killing their own direct opponent and where indeed they could have indirect fire from their sides when they push too far too quick, where they could have indirect fire from arty or planes.
Same thing with players doing 4vs4 on 2vs2 - 3vs3 maps.
You may consider it's a shitty way to play the game, it's your liberty, but do not call to delete it.
