ive edited a few of those as well, as a general rule of thumb, write analysis for the pokemon not the beginning stages of 5th gen (this was terrible in golurk's ou)
however, i should note in:
"With the new sleep mechanics..."
"Dragonite's new ability, Multiscale..."
i dont see much of a problem, as these changes are new to 5th gen in general are directly relate to the pokemon - multiscale is still dnites new ability in 5th gen. its probably preferred if you dont do that but in those cases, its not a big deal
