I wouldn't go that far. My warlock uses Pact of the Blade, the Mobile feat, and judicious use of Expeditious Retreat to do pretty well without Eldritch Blast.
That's a lot of resources just to get back up to the baseline. Eldritch Blast (and agonizing blast) should have just been class features. They are so powerful that you're just shooting yourself in the foot to ignore them (or going the attention seeking special snowflake route).
Personally I give them for free, (and Pact of Blade thirsting blade/extra attack for free) and warlocks still don't seem overpowered.
