Um, no. After the top 4, second tier is: Zangeif, Rolento, Sakura
Sakura is still very solid with the best cross-up games in the cast. She’s very near the top.
Rose CCs? Why bother? CCs are the last thing you’ll be wanting to spend her meter on. Level 1 Illusion, Level 1 Soul Throw, and both ACs are far better options than her CCs. But if you must:
Rose CC1: cr.HK, LK Soul Spiral xN, HP Soul Throw
Rose CC2: (with charged fireball), cr.HK, LP Soul Spark xN
Ken CC: cr.HK, HK Hurricane Kick xN, HP Dragon Punch
