That's a good question. I guess I'm talking about the Public Opinion Bard. Or the Medieval Bard...because for some reason Ed Sheeran is cool (level 12 halfling (modern) bard) but this guy isn't:

It's kind of weird for bards to fill a "tactical" niche, because realistically, if you're effective in combat it means that you've been neglecting your musical talents. But since you're talking D&D that makes sense, given the Three Pillar System: COMBAT! Exploration. social
Traveling troubadour: possibly. Sex scenes don't convert well to RPGs.
Celtic bard: sounds like those are good to go.
Folk hero: will need some saving if the common folk wield common weapons.
Singing warrior: might get beat up by the warrior with raw strength.
The bards I've seen hold their own well enough in a fight with support tactics such as spells of even using the help action. If they decided to take a more martial role then the trade off is being less effective in their support role. It seems fair really; otherwise every other class needs to ask the question of "well the bard gets all that for combat, what do I get in the social and exploration pillar?"
