What unit do you think would be most useful in AA and how? Edit: Forgot to mention that it's relevant because I'm not sure, yet, what 5* weapons/skills to merge down on them exactly. My thoughts: Olivia is pretty fine, just needs her skills upgraded, so just Ruby Sword+ from a Seth and waiting for the right fodder (Fury3, WoM3, Moonbow) would be required. Sophia is already a butt-saver in AA the way she is but could sure do better with slight upgrades. With Est & Cherche I have no idea. Maybe just add them to my armored effective pool with their original weapons (would be very cost effective). Lissa is probably the most expensive to build and I don't have any rare healer fodder for wrazzle-dazzle combo but since it was a thing I wanted a Pain+ + double Savage Blow Healer build. Should I consider her?
