Unless the jutsu is limited to 30% chakra in its nature, and wasn't just decided on so they could continue to perform the extraction. The way I see it, every jutsu in the Naruto world has to have a counter, or a weak point. What if the weak point of the "Meat Puppet Jutsu" (I like that name...) is that no more than 30% of the user's Chakra can be used under any conditions? I think that would make a suitable weakness, and it would limit the jutsu to allow Akatsuki to defeat weak enemies, create distractions, and reconnaissance. On the other hand....what if the jutsu were limited by the container (the possessed body) being only able to hold the maximum amount of chakra which the original body was able to hold? Though that's unlikely, as Neji was able to see Kisame's enormous chakra....but still, it's a thought.Originally Posted by DarthEnder
