Well, tiers can change over time.
It's not a big deal anyway. Like Rutger said, every character is represented at SBO, and while some may seem a bit underwhelming, I don't think anyone is unviable. You just might have to try a little harder to win.
I'm sure Akihiko and Yosuke are still very good characters, just maybe not as good as some of the others.
On an unrelated note, fighting against Elizabeth is annoying. :I
