You can already tell the combat is going to have a lot of depth even from it just basically being the tutorial level. Things like executing a charge attack at the same time as switching character to have no down time etc.
I don't see people talking about how hard first boss was though(not here in particular but seeing people on internet saying its too hard and they had to drop difficulty to easy lol what), game literally throws like 30 potions at you. You can absolutely just face roll and brute force your way through the fight(as you should be able to since tutorial boss).
