Well to say that CCQ is Ddraigs full potential is kinda 50/50. While CCQ has the potential to grow or even surpass the JD in terms of power alone, yet CCQ is different to what Ddraig or any of his possessors gone to as the all of them go for destruction, Issei went one that tends to a calmer or protective side; and this mainly because of the evil pieces tune up, the aligment with the other users, and part of Albions power.

Even the LS wasn't possible at the time if Issei didn't stole Albions power, and the Two Heavenly Dragons understanding each other after eons of battles. Not to mention that the first ability to be released because of this was [Reflect]. And [Penetrate] is also down the line of [Reflect].

Though none of these things wouldn't have happen if it wasn't for Rizevim (the unlocking of abilities that is). Now the unlocking of [Reduce] and Blazing Inferno of Scorching Flames (I still feel that is should be said backwards) are more with the concept of accepting who and what they are, the aceptance of oneself; or clarity of the heart. Such case is for Albion and Vali, hell I think even Issei.

I'm gonna need time to re-read about this last point since I don't remember well. But anyone is welcomed to agree or disagree
