Reworks vs New Champions

So, the idea of reworks is to modernize an old, no longer functional kit or at least outdated kit.

The idea of a champion release is to release a modern, functional kit.

Now, why exactly are these two things so different?

The reworks all scream counterplay on every button on the keyboard-- Veigar and Sion cant even use most of their abilities without people just hopping away from them.

New champions scream overloaded. I honestly don't know what else to say about this. A champion really shouldn't have everything ever other champion could dream of. There is a checklist of available categories for a champion to dip from--

Range, Mobility, Survivability, Utility(and under this, Crowd Control), Reliability, and Damage. Now why in the world do new champion releases get to hit most, if not all of these categories?

I know he was just released, but Ekko has just about everything in the list except for maybe the Reliability of his ult doing damage? And since he was just released, his numbers are also absolutely absurd. 80% MS Slow, 60% MS slow, a reset button (what assassin isn't complete with the thing that makes people hate assassins the most?), damage everywhere including the reset button, and even a stun. At least they nerfed the stun down from 3 seconds.

Yes, you can probably go through a kit and peg all of their advantages and make anything sound amazing, but why do reworks get pegged with "counterplay" through their kits to modernize them, and the actual modern champions just get to ignore this apparently golden rule?

How are old champions ever going to compete if we don't re-release them with the same standards that new champions are released at? It just doesn't seem fair to anybody who actually wants to play the old champions-- immobile, less damage, less survivability, less damage, less utility, and low reliability.
