The only "you" problem here is you presuming to speak for a hivemind of fans and making crappy false dichotomies.
There is a vast abyss of difference between removing spell slots and just changing warlock to have more warlock spell slots at lv12 and make them lv6 spell slots. Even giving them a total of 4 spells at lv6 and increasing their spell book so they can learn Dethrone and Disintegrate if not Chain Lightning would be a start. In a battle my wizard can cast 2 lv6 spells, 4 level 5 spells, and even a lv3 magic missiles with clown gloves will outdamage anything my warlock can cast at lv5. All while the wizard has spell sculpting and a vastly bigger spellbook. Eldritch Blast does not come even close to closing this gap.
90% of the warlock leveling invocations are absolutely worthless. lv9 invocation to get some crappy minor summons that other classes get at lv7 and don't even use, because the minor elementals are garbage for the spell slot they cost. 55-65% hit chance attacks that don't even do that much damage.
Pact of the Chain imp gets a single extra attack, stays at 10 minuscule HP by lv12. Archfey and Eldritch pact warlocks don't even get thematically appropriate summons.
The gap between sorc/wizard and warlock is humongous, and just because you can create a paladin/warlock hybrid that mostly is a paladin with a few warlock perks in playstyle does not mean that people who want to be a pure warlock without being an undertuned pile of garbage with mostly dead/obsolete leveling perks should be happy with what they got.
You might want to read the posts I was replying to. We weren’t talking about whether wizards are better than warlocks or multiclassing, but casting spells in general and the fact that you need to rest to recharge slots.
What your wizard can do in battle appears to contradict the thing I was refuting, that “They do not want you to cast spells and this is ridiculous”
