Future Diver Class Roster Update

I know its a while off (sometime after preseason), but here's the Big Four I believe would be getting significant changes in this particular update.

Aatrox

Olaf

Pantheon

Shyvana

As to why I selected these 4 is due to several reasons. All of which other than Pantheon have too similar of play styles, not giving them enough uniqueness other than diving in and auto-attack things with a few rotations of spells.

Shyvana and Aatrox both suffer from not having much reason to choose them over other champions, for example Olaf you pick if you wish to ignore all the CC on an enemy team in order to single out a threat. Olaf along with Pantheon I feel are just old kits that need quite a bit of updating. Although I'd say Aatrox would need the largest changes.

There's not many that fit into this class imo, but what are your thoughts on who riot should look at most?

Here's the rest I see classified as "Divers" that I can think of,

Diana

Hecarim

Jarvan IV

Nocturne

Pantheon

Vi

Xin Zhao

Feel free to share your thoughts, and be polite with one another. ^^
