That's fair. I was just under the assumption that Nagato might barely be fast enough to react to the Raikage, simply because Obito at the Five Kage Summit reacted quick enough to go intangible. Hence, I think if Nagato knew Raikage was hurtling towards him, he'd be quick enough to trigger a Shinra Tensei without the need to use his arms or say "Shinra Tensei", kind of like when he fought Kakashi.

I also forget that Nagato is a master sensor as well, Nagato could perhaps use his Rain Tiger At Will technique to cover the surrounding area around him with rain, so he can detect all of the 5 Kage's movements. Although he might be able to do so without the rain anyways.
