Wall level 5th form

[Gojii-san]

Given how Shin is perfectly capable of synthesizing completely elements on a whim and his land forms are already partially composed of stupidly durable materials that prevent him from collapsing onto himself by simply existing (let alone moving much faster than any creator of his size should), shouldn't these things be "At Least Wall Level" instead? After all, we don't know what they are made of and we can't assume that it's anything normal.

I know that they are not viable for any matches due to having no feats at all, but it bothers the hell outta me.
