Performer (bard) class

I successfully wrote a small (15 page) TTRPG book. I made V 0.1 "Alpha" and playtested. The biggest problem is that I basically forgot the bard class. Not even joking. (Also I was devastated when no one played a magician bc I made a real fine magic system.

The real problem: I love DnD's approach of bards being ond of the most versatile class, but I also feel a that they're a bit OP (in 5E). Share your thoughts!

Clarifying: My game isn't a DnD variation at all, I just wanted to make it an example.
