Charge characters are underpowered in AE. The best was Bison and that aint saying much. In super, they were overated. A couple of them dominated the low tiers but when it came to fighting top tier characters in high level tournies, it was very hard to compete. For some reason, people forget who was dominant in super. I remember Abel, Fei Long, Viper, Akuma, Cammy and Rufus. Boxer, Dictator, Guile and Chun was good but not dominant.
Now if you look at the top characters at the end of super, you will notice that they have some things in common. They could produce high damage in many situations, create more big damage after a knock down and could punish you hard with OS.
