New Champ Class Idea

Okay, so I have been really thinking about this champion class for a really long awhile now. Perhaps you guys can help me add to it?

It's called, 'Scout.'

Basically this class is really a mix between the typical jungler and ADC.

So they are basically really super agile, quick, speedy, aware, and just like an overall really super speedy and fast champion class that realizes their position in the game quicker than anyone and really like it's for people who main all roles.

Basically, I really want a champ that has like 400 speed to start, so you can play all lanes with no problem. It's because I really main all roles and I really just want to be everywhere helping everyone! <3

Like to introduce this class into the game, I'm thinking like a really cool combination between Elise, Janna and Vayne?
