Deactivate minecraft hit time reload?

I have been there since 1.7 and had stopped for a few years and now I'm annoyed that the damage will be less as soon as I do not wait until this reload has ended under the crosshairs. How do I get this away in the single player in 15.2?

Changing the version to 1.8.9 or below is not possible without mods / plugins.

There should be mods or something for that. But if I were you, I would just give it a try. I played without hitdelay for about 5-6 years and find the new system much better. The hitdelay makes the game a bit more demanding because you can no longer just blunt the left mouse button.

That makes the game much worse, it should also be about the cps, now it is only about who exactly waits for the delay and it shouldn't be about WAITING.

This may apply to pvp, but not minecraft itself. Because cps is pretty much the least important. Other than that, you've probably never played 1.9+ pvp before. This is much more than just waiting. You can be good or bad there too. The main thing is that you have to aim much better since the few should hit.
