Old Patches Game Mode

So I was thinking about all the patches I've played and that's quite a few. I got to thinking and had the idea that one of riots game modes should be an "old patches game mod" where not all but most of the changes that were made in a certain patch could be reintroduced in that game mode. Now there are some patches people hated but there are some that people LOVED. And it doesn't really have to be everything, it could be just champions with their old visuals and abilities but with an updated look so it can fit into the game. Just an idea that could really be something awesome one day. Post ideas branched off this or formed from this below! This would give older lol players a chance to reminisce and new ones to experience everything the old ones did!
