It's not that common, but yes. However, you could polish the gameplay all you like, but if only 1 character is used, then when you make another you may have to make changes. Because by then it was clear the game worked just fine...for that 1 character. But the 2nd one was never used while the game was being tested, so they may force the devs to change some things for it to be useful/not-OP/not break the game.

The gameplay with Ruby is rather fine, excluding how her special skills are rather too impractical and 1 is borderline useless. They may think the gameplay is fine as it is now. But then Yang comes, and her special skills and attacks make the gameplay not be as fine as it was when only Ruby was there.
