Gamemode - Throwback (Suggestion)

Ok, I have a custom gamemode idea rattling around in my head, and I want to get it out there. I know that this idea probably won't be used, but here it is if you want to use it, for nostalgia's sake:

Throwback is one of the gamemode rotations, where everything that has had a rework or new look gets returned to the original, or at least a few updates back. For instance, Sona's W (Aria of Perseverance) returns to This. I'm not saying that champions that have had nerfs or buffs should return to their broken or weak state, just that champions that have had major reworks (like Ryze) would be returned to their former state. I know this is a bit of a long shot (and it would take a HUGE update for people who haven't played the game for too long) but I really would like to see this implemented!

(I realized after posting this that I didn't add a poll, so please speak your mind in the comments below! Thanks!)
