-You can either kill the side enemies before focusing on the center (taking each side a time) or you can try to kill the center enemies as fast as possible. Taking the boss first is good if your team has enough dmg for the tankiest ones, but if it doesn't then take the side enemies and control the center with sleep and other statuses.
-Don't waste crit buffs on fights against regular enemy groups
-Get yourself the support units who can buff speed and/or heal (ex. Skyla)
-Get yourserlf tanky units (ex. Dawn)
