Huh? What are you talking about? Vali did size up Crom at the beginning when he first fought him in his Emperio Juggernaught Drive. Crom totally thrashed him. Wnen Vali realized he had no chance in that form, he went to his DxD L to fight Crom seriously. It's you who have not been paying attention. As for Crom, he stated that wasn't a difference in power betweem his human form and dragon form so that's irrelevant.
