Well it is the physiology of the weapon itself that allows for this to happen. And I know that I was instructed that Masa's clones could only do dmg as Samehadamaku, but not the cp damage.
Which is pretty fair considering everyone has low cp pools in this guild and if I were to make my 7 water clones and go nuts on somebody (Given the old dodge system) I could kill a Jonin Commander easily.
Now the only thing stopping that is lady luck.
I dunno I'm a bit surprised about this since I've never heard of such a directive... and I've played a Hoshigaki for quite a while. Even when Hiru had a Samehadamaku, its clones had always drained cp, even in fights with Kouri when we were testing out the system.
The physical clones do just that, copy the exact physiology of the user which makes them nearly indistinguishable from the user itself. If the clones themselves can do their jutsus and limits, I see no reason why it shouldn't apply to the clones of Samehadamakus or Samehada. It would also go against the very objective of the clone since as soon as you'd get hit by one you'd know right away that its a fake, since no chakra was drained...
If it is a balance issue that concerns you, we could look it up in a fight with two individuals of the same level. But for the multiple clones, we made many adjustments to prevent just that type of exploit (because there were a lot before). First it would be
extremely risky to make 7 water clones because it does divide your cp by 7 plus substract the 7 base costs of 15-25 each...let's not forget that 0 cp = death. Also, most clones will go down after a single hit, which makes it a huge risk for the chakra cost (Just in that fight Hiru's single clone cost him 199 Chakra, that's basically equivalent to an A to S-Rank technique!).
I understand for characters with low chakra pools this would be a problem, but that's why caps were made to the maximum drainage of the blades. People who make miniature chakra pools should know it is a risk. Poor devellopment isn't really as much a system issue as an individual character issue.
