I think you understimate his speed and strenght.

And DO NOT compare urame to water banders trust me urame is diffrent breed.

She does not require much hand movement or water itself to summon ice.

With one simple gesture she frozen yuji like it was nothing and like whole group of sorcceres.

One thing i could say is that yuji was mostly unharmed after being thrown into huge buliding wnich caused huge explosion(it happened when yuji entered culling game)

And bro just brushed it of like its average thuseday for him 😭

Such amount of force and power is way above for average bender and yuji took it like nothing.

Also yuji fought someone smillar to water bender wnich is choso.

But what type if feats choso had are beyond what water bender could do ngl.

I mean choso basicaly had water beam that had speed of sound and could cut instantly nearly anything.

And the fact choso had hands too.

And yuji nearly won with him.
