Yes, Bleu completely overrides Nina as a character in the gameplay mechanics. She has the highest growth in almost every parameter because her statistical growth increases even at levels where other characters' stop gaining points in various statistics.

Rose was fairly powerful in Street Fighter Alpha 2. If I recall correctly, Rose, Chun-Li, Ryu, and Ken make up the top tier by themselves.
