I don't believe for a second that Tatsuya can't one-shot Suzaku, if the comparison with weapons are correct and Tatsuya is at the level of a strategic nuclear missile there's no reason he can't. Also how do you not get one-shotted by wall hax with sniping capabilities, dispersing substances at molecular level, cheat cast, near instant regeneration, cast jamming, super engineer/spell inventing genius, ninja + whatever Material Burst is? I mean just Flash Cast and Tatuya is broken OP, able to remember any spell and then cast it without using a CAD or a sequence?
