Well, Bard is supposed to be the Jack of all Trades class, and in D&D3 (and thus BG3) they very nearly are the Master of all Trades class, so much so that if they would make Bard any stronger, even I, a fan of the Bard class, would complain they are overpowered.
Feels really good, too, because Bards have been seriously underpowered in D&D2 and D&D3, where I refused to touch them, despite liking the idea of the class. But they just had too many gross drawbacks. Now all the issues have been fixed, Bards can cast spells in armor, Bards can take over for a Rogue, Bards have their own spell list, Bards are full spellcasters like Wizards and Sorcerers and Clerics and Druids; really my only remaining complaint is in order to get Bard Inspiration on a Bard you need a second Bard, a detail that still brandmarks the Bard as the enternal sidekick.
As already mentioned by others, the Bard College of Swords might already be overpowered, so those Flourishes probably should be fixed.
But I honestly cant see much use for the Bard College of Valor, unless you would want to play a tank Bard. But even in that case I would probably dip into one level of Life Domain Cleric, to get heavy armor as well, and go for Lore Bard otherwise. You miss out on the extra attack of course, but you get the Cutting Words and of course the extra skills and spells.
