Yes, that is how Spit IX shall be used. It means you shall engage only when you have an energy advantage, and disengage when you has energy disadvantage. And when spit can't ran away, which happens often, it still can turn the table by careful e managment, building your e, and wastng enemy e. It may be borring, but if we speak it terms of K : D its how it shall be flown. Putting it into turn fights at every possible case is wasting big part of its potential. At least its how I understand it.
Yes, even 202 can be an energy fighter, if used as an energy fighter, but it just not good for this role against MA plane set.
