This map is nearly impossible to defend. If you play attack first and you go something like 6w 6L, you will most likely lose the match. You need to go like 10/2 on attack to have any chance of winning.
I've also come to the conclusion that on this map you only need like one duellist. You need a team stacked with info and defending agents... so something like KJ/Sova/Fade/Viper/Jett is a good combination for this map, to get quick info so team can rotate fast, find all the lurkers coming behing to stop you getting shot in the back every round by someone lurking in spawn.
