NO new invocations? Why? Not even in Arcana Unleashed?

I couldn't understand why some awesome third party books, with dark, warlocky flavour were releashed with zero invocations in them. Even the new Ravenloft book had none. But now the "magic" book, the book that will feel like Xanathar's/Tasha's doesn't have ANY invocations?

Wizards ... why no love? Locks need some interesting, use on demand powers to make up for their weak spell casting and the fact that there are no feats that increase damage on eldritch blast (just look at the eldritch blast damage assessments ... it needs love). 

Thanks!

They have a unique design which makes creating content for them not generally applicable. so they produce less for them. Heck like look at that path of the lich stuff in unearthed arcana arcane restoration caps at 4th level spells. Maybe an oversight, they should have said a pact slot or a spell of x level calculation. But it stops warlocks from using it once they get 5th level slots. Not giving them content, a horrific spell list, invocations that peter out at a pretty low level, oversights like arcane restoration in the end makes it feel like they do not like warlocks. 

Reminder.  Via lessons of the first ones all origin feats are warlock invocations.  That has generally been more than enough power creep for me.

 What? The spell that, with one invocation, does more damage than a 20th level fighter with a longbow at 17th level, and with another invocation, pushes enemies back up to 40 feet, on a class with up to 4 fifth level spell slots per day, isn't good enough?

Marun ... you should check your math. Tons of videos online ... EB is weak. 

Eldritch Blast does the same damage as a heavy crossbow and is considered one of the best cantrips in the game, especially when paired with the right invocations, and the fact that you also get 2 beams at 5th, 3 at 11th, and 4 at 17th level. Warlocks are NOT underpowered.
