Obviously, as Rose, you don’t want to throw fireballs agaisn’t Chun since she can punish them easily with hazanshu. Chun on the other hand **can **throw fireballs since she can get around reflects with hazanshu. Once you stop reflecting, Chun can use her fireballs to get around your pokes. Chun has great pokes, great focus to counter your slide, safejump after sweep knockdown and cr.hp x legs pressure which you can’t really do anything about. Besides, Chun with U1 will shut down your reflects, and once she gets that super you are extremely limited. I mean, you can’t even use cr.mp on her block. And the footsie battle will be in her favour because of her st.mp x super. In AE, Chun has more tools to break down Rose.
And the makoto matchup is far away from 7-3. Sure, it may seem correct against crap Makoto’s that haven’t learned that they don’t need to respect Rose’s options. They for sure will have trouble getting in. But the good ones - nah ah. The only thing she might have to watch out for is EX Soul Throw since it’s damaging and sets up for the untechable knockdown. Once she gets in (which really isn’t that hard for her) it’s a complete guessing game for Rose.
