Naruto Shippuuden Episode 301

...why exactly...is it natural to assume that this MAGIC power is going to have some kind of Wi-fi latency?

Because we just saw it happen? It's easily explained by zombie Raikage not being as fast as he was while still alive. That slowing down, which isn't caused by rotting flesh like you said, has to be caused by something and since we know for a fact he was being remote controlled, it's either lag in the communication itself or perhaps Kabuto's brain couldn't keep up. He's not exactly a master of fast techniques himself, quite the opposite, since he's a medical ninja. A medical ninja needs accuracy and precise control, not speed.

No...what we just saw happen was you just wrote some fanfic to try and explain away a plothole.

There's never been any indication of a delay, so you can't just assume there is one when a character doesn't react as fast as they should.
