Rewind about 20 chapters or so and we were told of the awesome Bloodline Expansion that only the Tsuchikage was supposed to have. Now I remember back when Bloodline Expansion was introduced to us, we all pretty much over hyped it and people made some pretty crazy speculations about it.
Now however, like most things introduced back towards the beginning of the war *cough* Kakashi's rampage. *cough*, it seems that Kishi either has forgotten about Bloodline Expansion, or it simply wasnt meant to be important enough to the story.
We havent really seen what the Bloodline Expansion can do, and because its been so long since it was brought up some could think that it simply was overhyped or was just skipped.
Which brings me to my question for you all. Do you think that Bloodline Expansion is/was overrated, or underrated?
