Something i think that would be healthy for LoL

If the next 20 champs released, were incredibly similar to current champs, with only the slightest of differences.

Example: Tryndamere, Barbarian King. compared to Golrod, The Destroyer.

Passive- Rage system(name it whatever)

Q- Passive AD. Kills, and critical strikes generate Rage, Rage increases Critical hit damage, rather than critical hit chance.

Similar E- A leap smash, instead of a spin.(Same distance, same purpose, same scaling) Only difference is, its a faster movement than Trynds Q, and it doesn't hit everything in its path, but rather only where it lands.

W- Goldrod lets out a battlecry and roots all targets in X radius for 0.25seconds, and slows them by 25% for 5seconds.

R- literally the same exact thing.

I just think it would be nice to play certain champs, in a completely different theme appearance wise. And to have the option to play your fav champ, just slightly different. I think we have way more than enough champ diversity, that's for sure.
