Worthy to note, at 2nd level Jack-of-All-Trades is one of the most pft overlooked and OP early boosts in the game. You are at least half proficient with anything with which you are not fully proficient. This would include greatswords, as well as initiative, per RAW, confirmed and legit bard power plays. Be sure to always inspire, always jackofalltrades, and always song of rest (did I mention vicious mockery?) As a low level bard you will be a hero at all times to your adventuring party.
Also variant human+ritual casting wizard familiar amongst other gems = nice healing touch delivery if your party needs some healing support. I love being the most versatile character on the map at all times and still being a potent purecasting arcana beethoven sorcerer/maestro. I may give greatsword a go though, I had been considering a greatsword ranger but I just dont love them like I love bard... Still not sure I could go valor vs lore though.... Access to every spell in the game cross class cherry picking could make for a very nasty great weapon fighter. Warcaster would be nice to flavor in a singing greatsword mmmmm
