Yeah, Raph's current 66B used to 44B in SC3. That move was an excellent option for whiff punishment. The slight backstep and then lunging stab had great evasion, range, damage, and RO potential. 66B in SC4 didn't RO anymore, but stunned, did less damage, went into Prep, and gave a free combo. So it was a trade off. It would be nice if they moved 66B back to 44B (this move has GB in SCV too), move 3B back to 66B, and make 3B his old launcher. This is probably asking too much, but anyway....
Futhermore rather than having SC4 Prep A+B in neutral, why not remove it and give him back his SCIII Prep B+K? Both moves have similar properties in that they duck highs followed by a powerful stab. Prep A+B was slow, linear and unsafe. Prep B+K was fast, did good damage, and could RO, which Prep A+B cannot. In SC4 Amy had his Prep B+K. Im still mad at her for stealing all his good moves. Why does Raph have to change from a beast in SC2 to an underdog in SC4??? His fighting style, charisma, and frames deserve more respect in my opinion.
