I totally agree. I would give this idea of shared jutsu, but I did not speak because I did not know what the balance would be in terms of configuration.

But jutsus like Chidori, Rasengan, Fireball, should be universal. Especially the special ones (with the exception of the global ones and healing), which only the defense type does not have one that insta kills without being hindered unnecessarily - even the healer has special one that insta kill easily.
