Eldritch blast is essentially a feature that they let you opt out of, or let you opt to diminish in favor of extra tricks. It is not overpowered. Yes, d10+d6+3 at 2nd level is solid, but 4d10+4d6+20 (if you devote a spell slot to hex) at 17th level is about as much as a big weapon melee character does in 2 attacks unmodified. I find my high level warlocks don't use it very often, instead using their warlock spell slots, a staff, or spells - . They just use it to finish off a foe or to push an enemy around a bit if we need to maneuver them.
In a recent adventure, my 17th level warlock (with a Staff of Frost, Pearl of Power and Rod of the Pact Keeper +2)
Combat 1: He True Polymorphed into a Dragon and fought as a dragon.
Combat 2: Still a dragon. Roar.
Combat 3: Rd 1: Banishment for 2 enemies. Rd 2: Staff of Frost for Cone of Cold. Rd 3: Eldritch Blast - knocked a giant off a cliff. Rd 4: Eldritch blast to help finish off last combatant.
Short Rest.
Combat 4: Dominate Monster. That ended the battle versus a solo monster.
Combat 5: Rd 1: Mass Suggestion. Rd 2: Cone of Cold. Rd 3: Plane Shift vs enemy. Rd 4, 5 and 6: Eldritch blast versus trapped foes.
Combat 6: Rd 1: Banishment vs 2 enemies. Rd 2: Banishment again (concentration lapse). Rd 3: Misty Step and Eldritch Blast.
Long Rest.
