i prefer soft caps, scpecially with your mons doesn't obey you mid-battle as i like having a blaziken or a charizard against shelly or noivern against aya it makes it feel realistic but with the rejuvenation hard cap i can't have a good mon against keta
so each has his advantages i wish in future episodes they would have an option to choose either to play hard caps or soft caps plus the hard caps makes common candies (or whatever they are called in rejuv) useless
