I'm not sure I like limiting them based on pact though. Why does the Chainlock get the improved healing for instance, and why can't my bladelock never sleep.
I get the feeling that the Chainlock is really more of a GOO'lock thing, and the no sleep thing? Well, that's a classic Fey, not needing sleep thing. So...
We also need more special Familiars for Chain-pact Warlocks so we can match to the Great Old One and the Celestial. Fiend and Archfey already have two thematically-appropriate choices each.
Pseudo-dragon is the GOO familiar; they're both psychic and telepathic. You're right about the Celestial familiar needed, but GOO and fey have one each, while fiend gets two.
The Eldritch Smite looks like a poor choice, IMO. The Warlock has so few spell slots that a simple +Xd8 damage on one melee attack hardly seems worth it.
But it also knocks prone, which is huge. That's a great set up for lots of tactics.
The difference is that the paladin has more spell slots, albeit lower-level ones. Up to 10th level, the warlock only has two spell slots (per short rest), while the 10th level paladin has a total of 9 slots of 1st through 3rd level.
And the warlock's slots can generally be used to do more interesting things. Blight with a 5th level slot would deal 9d8 (save for half). A fiend-pact warlock could fireball for 10d6. Or you could cast fly, hold monster, or hypnotic pattern.
Not more interesting if you want to be a melee weapon user. For those who want to hit things with their blade, its a welcome addition.
I do think maybe Celestial Patron needs to be toned down a bit, it's a lot more powerful then the other Patrons.
I think you mean -less- powerful. Sure, the healing is good, but +Cha damage to ONE target on a fire or radiant spell still puts you behind Eldritch Blast and Hex / fireball abilities on a fiend warlock. Heck. Celestial Patron doesn't even give fireball. Unless you take the Mephistopheles ability, I suppose, but +CHA to one creature is still not a big jump in damage at this point after everything else involved.
Apologies if this has been touched upon already, but can we assume by the introduction of Frost Blast and Gift of the Seas to the Warlocks Invoke list that the Sea Sorcerer didn't make the final cut and instead got folded into the Celestial Warlock?

Nah. Frost Blast is because Winter Court / cold magics is a thing with 4e fey warlocks. Gift of the Seas is something to enable more sea-faring classes, not baning them. It says nothing about the Sea Sorcerer.
I didn't realise anyone disliked them being tied to Patrons. It made patron choice more impactful.
As someone who requires story to make sense, I don't have an issue at my table of non-fiend warlocks even thinking about something named after an archdevil.

On the Maddening Hex the King bit... The king, no matter how smart or dumb you make him?
Is taking damage. How is that not obvious that something is immediately happening? Maybe our warlock is in a crowd, wearing a cloak, no one pays attention to the weirdo cloaking their magic because its hard to tell. The king is still suddenly going to be in pain. Its going to be obvious there's damage, if only a sudden migrain.
And, unless your king is pretty laize faire about magic users in his country, I imagine there's going to be a few as guards, as well as a healer nearby that could remove the curse, or at least keep the hp high enough until someone can diagnose and remove the curse. Realistically, I can't see this happening, just because it requires the king to have no magical backup, and the damage to be unnoticed.
Are there some situations this could be used to kill someone? Absolutely. And that'd make an awesome story. But anyone anywhere with some stealth rolls? Not likely.
