He was prompt at pre 3.0.

As soon as 3.0 released he got changed to non-prompt.

As for Breakthrough, his barrier cast is still non-prompt, but adds immobile and shields.

Nope, before 3.0 only Gaara has prompt barrier. I played him all the time.

In Matsuri, I had him in front row and waited for opponent's Hashirama to cast and then i casted it over all the time.

Now 3.0, all barrier becomes non-prompt.

When 3.0 was out, I didn't read which ninjas had changed, I only noticed when I played him a few days after.

Cos I remembered I had to re-do my Ranked Teams and such.
