The drop rates in this are a joke! Aerith, Jeume, Christmas Luartha and now Moore (CNY version) all had to max the gauge to get them. Add to that the fact that the AI is an absolute joke - just watch the stupid AI make your units clump to spam unhelpful status effects and... yep the enemy can just drop AOEs on the top of them and screw them all! Oh and you can't just skip some of the entire battles where AI is the only option and this sucks.
