About Transformation jutsu

[Warlocks]

I don't think the appearances is the only thing that changes, otherwise Gamabunta couldn't have claws by transforming into Kurama. By that logic if Gamabunta turns into a bird he should be able to fly since he has wings. If Gamabunto turns into a mole he should be able to dig.

and Gamabunta had tails

Problem with that logic is that Katon requires chakra, flying does not.

As a ninja would be using transformation jutsu he'd already have chakra.

It wasn't used anymore because Kishimoto realized how overpowered such a technique could be. Same with Kawarimi (Substitution Jutsu), which basically works like teleportation.

Probably no reason to I guess?

Well, maybe flying would be harder for them (as it doesn't come naturally to a person). Using claws is more basic. As for running away, trained humans have more stamina than cheetahs even in real life, and ninjas can already run/jump pretty fast, so I doubt they'd have much advantage if they transformed into a cheetah.

Then Ino must be very skilled.

Then Ino must be very skilled.

Yes, I actually thought about that, I remember her switching into a bird. I guess it could be assumed that she'd done it before and learned, or maybe Mind Transfer works in a different way. Though, we know that Kishi would never elaborate upon it.
