Well Crom Cruach is Heavenly Dragon level and has surpassed Ddraig and Albion when they were alive. And we really can't say that Issei is going to be way more powerful than Vali. I just believe that his remade body put him on equal footing with Vali in terms of potential. Let's not forget that with demonic powers, the sky is the limit. Look at what Sirzechs did with his demonic powers and his Power of Destruction. We have to remember that Vali is improving as well.
