Effectiveness, mostly. The class all but requires a maxed-out Charisma and Dexterity, or patches from other sourcebooks, to be able to keep up with other classes.
But I'm not giving up just yet.
And here you go. I just whipped this one up. I didn't really go for super-high damage or anything like that. I rolled 4d6 drop lowest in order and stuck entirely with the PH for all things (except for two spells and one musical instrument), kept the racial ASIs (ugh), and because of that, decided that this character is a scholar who wants to study orcs and goblinoids in order to better bridge the gaps between them and elves and to make peace between them.

Fey Ancestry: advantage on saves against being charmed and magic can't put me to sleep.
Trance: I can trance for 4 hours a day, gaining the benefits of 8 hours of sleep.
Researcher: If I attempt to learn or recall a piece of lore and fail, I can (usually) know where and from whom I can obtain the information.
Bardic Inspiration: two d6s. I regain all dice after a long rest.
Ritual Casting: I can cast any bard spell I know as a ritual if it has the ritual tag.
Jack of all Trades: I can add +1 to any skill roll I make that I'm not already proficient in.

Traits: By living among violent people, I have become desensitized to violence. I'm willing to listen to every side of an argument before I make my own judgment.
Ideals: By understanding other races and cultures, we learn to understand ourselves. The path to power and self-improvement is through knowledge.
Bonds: I've spent a huge amount of my life trying to understand the lives of people who are very different from me.
Flaw: I am easily distracted by the promise of information.
I mean, this might not be anyone's cup of tea, but this character is definitely not a smarmy, clownish, rapier-user. Their 1st-level spells allow them to (hopefully) interact with others in relative peace, and their 2nd-level slots are for getting out of Dodge quickly, if necessary. They used bardic expertise on Persuasion, so they can hopefully talk to the goblins and orcs they meet, and Athletics, so they can hopefully prove they're tough enough.
