Street Fighter IV producer Tomoaki Ayano has revealed today via the official blog (Japanese/English) that Ibuki's Okizeme (wake-up game) is a hot topic in the balance requests. He said they'll look into Okizeme in all characters not just Ibuki.
This's a very good news hearing that a lot of people brought this issue up (Ibuki's Okizeme) and Capcom acknowledged it.
People tend to overlook an issue if the character isn't popular.
1. When a character isn't popular, people don't see its potential.
2. Then that character became "low tier."
3. When a player picks it up and shows its potential later, people tend to think it's fine even if it's broken. Because that character is "low tier."
