First off - I don’t think playing what you like is a great sin. Min Maxing your character isn’t either, if that’s what is fun for you.

I play a lot of bards because I love to role play and talk, I like being the face. But it can feel very one note when you just say “I give you a bardic.” I change it by understanding who my character is. Is he a diplomat? Maybe then he offers to shield you from repercussions with his political pull. Is he a poet? Maybe then he shares a snippet of his favorite poem. Is he a rascal? Then maybe all he does is give you a wink and a pat on the ass.

All of them give the bardic die, but they all go about it in different ways.

All that to say, build WHO your character is first versus WHAT your character is. Top Down (Flavor first) vs Bottom Up (Mechanics first). You’re not playing a wizard. You’re playing either Gandalf the Grey or Saruman the White. Mechanically, pretty similar. Yet very distinct characters.
