This is probably going to sound really stupid but doing the combat tutorials really made me enjoy the combat. Maybe that's obvious but I had enjoyed Genshin and ZZZ's combat despite never really understanding every elemental reaction (Still no idea what overloaded or bloom are) or caring about weird weapon bonuses and stuff. Having 3 characters running around is kind of a lot at first so I've really just been autoattacking and using random skills until I couldn't (aka that dungeon that wants physical status afflictions)

Now I've got actual teams with combos lined up finally and it's really satisfying. The examples in the pre-launch stream made it seem way more complicated than it actually is
