So far, I've only played a couple level 1 one-shots, but I think 5e is amazing, the bard in particular. I don't so much have a question as I want to start a discussion about bard multiclassing. Here are my ideas:
Lore Bard 1 / Rogue 1 / and then work in one more level of rogue and 17 more of bard. Lots of expertise, jack of all trades, a life-saving disengage as a bonus action, and great spellcasting. The delayed +2 cha is a pain, but this feels like a really fun build.
Bard 1 / Rogue 1 / Cleric 1 / Bard+: There are a few ways to go here. Choose the Knowledge domain and Lore Bard for a ridiculous skill monkey - 6 expertise skills by level 5. Or take the War Domain for less dependency on Dex, letting you be more knowledge-based, or letting you be a front-line fighter when you want to. And Life Domain doesn't hurt, with heavy armor and the healing bonus.
Warlock 2 / Lore Bard+: A common choice, for the mighty Eldritch Blast. No need to ever get into melee. Or worry less about damage and get a couple nice invocations like Detect Magic and Silent Image at will.
Sorc3 / Lore Bard+: Lots of spells, and metamagic. Very tempting, but a 3-level multiclass means fewer feats.
Half-Elf Lore Bard 1 / Rogue 1 / Knowledge Cleric 1 / Warlock 2 / Bard+: This is the silly build that lets you have proficiency in every skill, and skill mastery in half of them. Probably not worth actually playing unless your DM lets you start with really high ability scores, but fun as a thought experiment.
