I'm still working on this too, but my progress was halted for a while by Atelier Ayesha. Now that I'm back on it, I made it to Labyrinth 3, and the enemies aren't giving me as much trouble as I expected them to. I replaced my Medic with an Arcanist, which still feels really weird, but I'm starting to get the hang of my new party dynamic. I miss Revive, but that's about it.
I'm excited to keep going! I have a feeling this game is going to be my standby for quite a while to come.
