Pseudo DXD Issei is near comparable with Ddraig, with DXDG Issei could be superior with the Heavenly Dragon class, Issei have defeat Apophis that have reach this level. Crom Cruach and DXD L Vali are both superior to Albion and Ddraig( in the volume 24 Albion said that Crom have exceed he and Ddraig in terms of raw power like aura and strength, DXD L can compete with Crom thanks his speed, so DXD G that is comparable with DXD L is above heavenly dragon class). Maybe when Issei facing Crom Cruach he could awekining the DXD G even for a short time, or he will defeat Crom Cruach working together with Ddraig.
