I'd say that it depends on the quests themselves and your own play style to build a team, but yeah, it's still better if you have insanely strong units so you could pass them all with flying colors. I clear most of them by my Nine Territory team and Sage Tower team, but I've seen other using knight units too. Just be patient and over the time you'll have a good team. Also, w atch other player's video may help you a lot in team building and timing experience, like, choosing the right moment to cast the skill. Some quests took me forever to finish too, so relax :)
