I would say its both and the reason is due to an interesting comment from Gokor. I remember Gokor saying something in the lines of " Ronda gets frustrated and takes critics too personal"
The thing is, Ronda comes from the Hayastan academy and although its mostly a Judo/Sambo/Catch wrestling MMA gym, they have solid boxing coaches and for kickboxing they have Benny the Jet who was a bad ass karate/kickboxer.
The thing is, whenever you learn a new martial arts, you will have to deal with frustration of tying to understand the nuances of that art. In boxing, you have to dedicate an insane amount of time on footwork alone. With Edmond, he shows ZERO footwork nor was he teaching her anything about distance management or learning how to use her lead hands.
All Edmond does/did with Ronda is pad work which is good for putting everything together but in Ronda's case, she has no specific boxing skills to put together and thus Ronda's boxing training was performed in a very superficial manner...
