I noticed something odd as I was playing version 5. Lany and Kyrie's attack damage during battle were really low. Both of them were doing less than 30 damage each attack. I went to check on version 4.15 and both of them were able to hit a couple hundred each attack. I started a new game in version 5 to check but they were still doing low damage. I am not sure if that is an intended change, if it is then it is hard to progress through the game when half the party does little damage. It is even harder when the party is split up.
