If I were inclined to make any changes, these are what come to mind at the moment:
1) Stop beating around the bush and just make Eldritch Blast a class feature while allowing Warlocks to select the same number of cantrips from a larger pool. This helps add more at-will magic to the class and frees players from always having Eldritch Blast sitting there screaming "Take me!"
1b) Additionally, make agonizing blast part of Eldritch Blast from the get-go and have Eldritch Blast scale with Warlock levels, no character levels. This removes what many feel is an "invocation tax" and reduces the likelihood of Warlock "dips" just to grab EB.
2) Give Pact of the Blade abilities that essentially mimic those of the Valor Bard. Some might not like this kind of "copy/pasta", but giving Bladelocks proficiency with medium armor, shields, and access to extra attack automatically at 6th level fixes just about every issue the pact has. You're no longer "taxed' to get extra attack and strength builds become much more viable without having to dip into fighter or paladin.
3) Invocations that grant a once per day spell don't also require the Warlock to expend a spell slot.
That's it off the top of my head. I like the class as is just fine, I haven't made any of these changes in my games, but I think the class would be the better for it if it's been built with some of these things in mind from the start.
