you can do 2 types of team: the yolo one, with this one you try to beat the quest/raid/trials dont spending too much time in this team you include generally critical, atk, spark buffers and generally high hitters (this team isnt very recommend for trials), and there is the consistent  team, in this one all your units have an important role, with this team you try to cover every area (reduce damage, nullifies ailement, atk/def buff etc).

you dont mentioned too much units to suggest a team but a can make you and idea with my raid/quest team: Claire(lead) - Zergel - Ivris - Luka - Shera. For quest I try to use a fill rate friend, and for raids I use Kurt (Colt for global players)
