Meh for my character it's more a case of what she will learn or is about to/very close to, I probably should have specified that but ah well. Plus, who said these characters were good at said techniques?

Well, you didn't specify that your character was not good with the techniques and seeing as your character can cast many different types of air style and earth style ninjutsu, it's fair to assume she is not inefficient with them. Saying "what if" doesn't really change the situation any. She's also classified as B-Rank. B-Rank: "It is preceded by C-rank and followed by A-rank. It is typically used when classifying techniques intended for ninja of the jōnin or chūnin level." Thus, that automatically tells me that she is skilled enough of a ninja to properly cast her ninjustu no problem. 

I specified that my character, specifically, was not good with his techniques to clarify that fact, Insomina. No "what ifs" or "maybes" or "could bes". If your character is bad with a certain technique, it should be specified rather than just something that appears out of convenience to make your character more balanced the moment is is brought up. lol Though I'm not pointing fingers or anything. It make sense to me that someone with as much chakra as the 9 tails could definitely do what your character can and more.
