Beat Shadow Rise last night. She was a bit of a challenge with a party around level 32 and I thought all was well. Then they pulled the rug out from under me and I had to fight Shadow Teddie. Luckily I had a Persona that nullified ice attacks, so it wasn't so bad, survival-wise. It just took ages.
Do the characters you don't use get experience at all? I left Kenji behind because he was a few good levels ahead of the rest of the party, but the sheer grind of Marakyu Lounge meant that they sailed right past him. Is it worth levelling everyone or is it better to just stick with a core team?
Rise seems a little flat so far, personality wise.
I stuck with a core team and didn't have any problems. Keeping more people leveled isn't bad, but it might be unnecessary and might lead to more days in the TV and fewer doing Social Links. I mainly focused on having an incredibly versatile MC for most fights.
