Is there anyway to tell when Goku is using regular Blue or the perfected one that he used against MZ? Or since he has perfected it, is he always in that state when he goes Blue? Either way, it seemed like he was holding back against Kale(like in the anime), as he seemed to be curious at how powerful she could become.
Golden Freeza doesn't seem to be Blue tier as he was stomped by Berserk Kale, who Goku more or less even with a likely suppressed Blue Goku. SSJ Cabba and SSJ Caulifia also seem to give him mild trouble.
Final Form Freeza is between Base and SSJ Caulifia. Makes sense as he had earlier waited for Frost to use up all of his stamina before fighting him, implying that a fresh Frost is pretty close or maybe even stronger than him.
