It is kinda strange though right?
Luffy do it better against Pageone and Ulti rather against Yamato. In that case Base Yamato was clear G3lvl+ and even had use her father attack, she is kinda op already in Base form. Now a simple question,how strong are the Flyers in compare to Luffy? G2/G3lvl or even above? Because Yamato was already in base stronger(it seems) then current G2/G3 Luffy. Not to forget that she has a similar op durability as her father,probably not as strong but she had a light version.
So a character who already have G3 lvl+ Ap
And a insane durability, she should stand already above any veteran right?
Add now the mystic Dragon power with the get, with should make her even far stronger?
I think alone by these informations I would place Yamato at commander lvl, she almost have everything to play with big dogs.
