For RP reasons :
Bards of the College of Valor are daring skalds whose tales keep alive the memory of the great heroes of the past, and thereby inspire a new generation of heroes. These bards gather in mead halls or around great bonfires to sing the deeds of the mighty, both past and present. They travel the land to witness great events firsthand and to ensure that the memory of those events doesn't pass from the world. With their songs, they inspire others to reach the same heights of accomplishment as the heroes of old.
And/or if you want to play a martially-minded Bard since you will now have "Combat Inspiration" and proficiencies in Medium Armor, Shield and Martial Weapons. That and an "Extra Attack" at level 6. Other sub-classes exist for bards that want to be more martially-minded but not in the PHB.
This is a fairly good option but not one that "min-maxers" would pick 🙂
