Sure will Issei surpass Shiva the same goes for Vali. Ise beat Apophis a dragon who achieved heavenly Dragon-Class in his actual DXD. Crome is stronger, than prime Dragi and Albion in his human form. So If Issei want to beat Crom in battlefield he needs to use AxA and not just his actual DxD mode. How can you say he never will be able to surpass Shiva.A year has passed an he is almost have the power of middle-class-God. Isei and Vali and the rest will gain power to defeat 666 so they need to surpass Shiva. Do not forget, that Issei is not a human, he is Dragon/devil hydride with a human soul. Ajuka stated, that all 8 Evil pieces turned into mutation pieces. You remember the site story where Ise´s kid were presented ? Gasper Vladi was also introduce as the mentor of Ise´s daughters. And Gaspaer suprass a super devil. And the 7 Maous have reached heavenly dragon class. So why do you think it is not possible for Ise to surpass Shiva? When Gasper in 30 Years will surpass Super devil.
