Urahara's zan

I think when someone attacks urahara's sheild, he should recieve the damage like when someone hit a hyuuga with Kaiten on.

It would be nice because sheild would be stronger and it wouldn't be oped

For techniques like Kido, the sheild should just make them change way like it would absorb the attack and return it in the way it came.( changing directions)

Urahara's zan would be stronger without being oped and sheild would be useful

No. The shield blocks all frontal attacks, except a couple, and it follows you around. Urahara has the biggest boost, and in bankai shoots two nake. Urahara is fine don't complain.
