If they give you the f2p version of ronin naruto (that in cn sometimes is available for 2400 ingots) what would be the point of buying ronin naruto for those out of mind prices?

The same is for mifune breaks. If you get them why would you spend for gnw madara to boost ronin naruto?

And shizuka, a free ninja, would be able to counter kakuzu eg sb/st too thanks to him.

Asking to oasis to be fair is like asking to a band of barbarians to behave.
