Satire is good too. Bonus movement is about equal to lore's ability to mess up people's attacks. It just depeds on weather you want to be more catwoman, or more manipulative.
Try hitting people with booming blade, and using the bonus action to disengage. They then have to trigger the secondary effect.
That was my fist idea also!! What puts me on doubt about this college are the other abilities. I don't know how to rate them, but they seem to be much less interesting than the lore bard skills.
As for 3...
Hex/blade smites is not too good. It requires you to hit with the greatsword, which means you don't get to use Cha to attack with, and you don't get your shield. You need Str, which otherwise you could dump.
I've only seen a very few situations where summoning a weapon would come in handy.
Darkness and level 2 slots are good, but you can only concentrate on 1 spell at a time. Bard has a lot of concentration spells. Hypnotic pattern, suggestion, etc... Which you are delaying for another level.
Now if you go tome or chain, it's ok.
I'll also just suggest rogue 2/hexblade 11/lore bard 3 . Which may fit your concept better than bard.
The greatsword options only would come into the game if, by any chance, I can put my hands over a ogre gauntlets or something alike. This invocation seems to be able to dish some big damage numbers. It will cost me 2 more warlock levels, but in exchange, it will save me a feat (you don't need a feat to cast spells with a 2 handed sword). But of course, I can't plan all my career around a magic item that may never appear.
About the darkness... I think that you have a point. Also, that spell will totally butcher my party's chances to hit anything on combat. There are better spells around (I just need to cherrypick them

)
If you're not really feeling the Invocations, I'd say either go Warlock 1 / Bard X, Sorcerer 1 / Bard X, or just straight Bard depending on what you're trying to do with the warlock levels. If it's just to have decent ranged and melee damage options (via eldritch blast and the blade cantrips), then I'd suggest picking up Magic Initiate as your first feat or as a variant human. Going with sorcerer can give you all those cantrips (well, not eldritch blast, but instead your pick of almost-as-good ranged cantrips) as well as the shield spell, and other bonuses (armor, burst flight, occasional advantage, cleric spells) depending on sorcerer subclass.
Every level you delay bard progression will hurt, so if you can go the Magic Initiate route (or Lore Bard L6 Magical Secrets route) to pick up what you really wanted from the Warlock class, instead of multiclassing, I'd say do that.
I think that I can make some alterations, like changing from Warlock 2/ Bard1 to Bard2/warlock 1, but I don't think that I'll be able to shift to sorcerer. The race is fixed too, so I can't take the magic initiate route.
But I suppose that you are right about the delayed magical progression. I had read somewhere that in 5e high casting levels aren't as importants as in past editions, and I simply accepted it without taking a look in detail to the spells (It's a big list, and it takes some time) I need to read them carefully.
I think that I'm going to be a bit conservative with the build for the moment, and I will go hexblade warlock1/bard 2. I can always get more warlock levels in the future, if needed. I have still some time until level 4, so I can make my choice between Lore or Satire without hurry.
BTW that "path to godhood" character concept is great.
Thank you, Sir!! I have another two bard-like characters on other games, and I tried my best to make them different between each other, so playing them doesn't gets boring.
-One is a Skald (viking bard) on a Yggdrasyl game. He was born as the seventh child of a distant Noble Jarl, and is totally a drunk, a scoundrel and a womanizer. He was kicked (literally) from his father's lands because he promised himself in marriage with too many women on different towns, just to start the celebrations, but he always ran away before the weeding. As far as the campaign goes, he is starting to change his behaviour, and assuming his role as a noble in the grand scheme of politics, and may became a good war leader, despite his efforts to avoid all those things.
-The other is a Pathfinder female Bard called Requiem. She had a twin that died days after they were born, and she claims that her sister spirit calls her from the other side (if that is true or she is just a bit mad is something that I left to the gm) She sings opera and burial songs in combat, and fights with a magical intelligent fauchard (a scyte-shaped reach weapon) that sings with her on the battlefield. She makes extensive use of the cantrip spell to make black roses appear around the corpses that she kills. She sometimes talks to the air and wanders around dancing in circles. But I also flavoured some spells, like saying that when she cast mirror image, the images are actually her dead twin, or the fact that when the weapons sings, the voice comes from her dead sister.
The rest of the party members are scared like hell of her.
