... I mean, of course. If you have sufficiently high chakra capacity, you're found by one of the villages, who abduct you and force you into a job where you're
88% likely to die before reaching twenty (are these numbers still roughly correct,
@Inferno Vulpix?). This has been going on for hundreds of years. There are very strong evolutionary pressures towards minimizing chakra capacity. It is
blindingly obvious, now that I think about it, and Isan is as blatant evidence for this as it can get. A literal control group. And Mist's shrinking imports... Did I somehow miss this before, or have we really not thought of it until now?
The real scorch squad was the ninja system all along.
