Diving Fighters - why i think it should be the next updated class

With this season updates on towers (nerfs), the Diving subclass of Fighters had lost their true identity.

Why are they called "Divers", when different champions from totally different classes can do the same thing, and sometimes, even much better than them:

Example of overpowered early tower diving champs : Ekko and Fizz as an Mage-Assassin type class Alistar as a Tank Zed as an AD Assassin

And you will find different scenarios early/mid/late-game when the above or other class champions have the tools to dive more succesfully than all of the Diving Fighters. Meanwhile, in teamfights, diving with the same above champions will always get better results than diving with Aatrox/Tryndamere/Jax, for example. Maybe only Xin Zhao and Vi would get you better results, but in ideal circumstances. Actually, we can give Vi as a good, balanced example : her entire kit encourages you to dive into a fight head-first and then worry about getting out later.

A Diving fighter should be less softer than a tank, but could still take some punishment, should kill slower than an assassin (Sated + guinsoo Xin Zhao), but SHOULD BRING SOMETHING WORTHWILE TO THE FIGHT, which doesn't happen right now with the majority of diving sub-class.
