Something that I would like to see.

Disclaimer: This is something that will probably never ever happen.

I loved League of Legends as a game back during Season 3. Enjoyed it during Season 4, but not on the same level. Season 5 is very meh, in my opinion. Earlier today, whilst playing a casual solo queue game, a thought popped into my head: People are joining this game every day, and they're only going to experience mid-Season 5 onward and miss everything from every season beforehand. What if, for each server (starting with NA, potentially branching out to other servers), we had several smaller servers that each pertained to a different period of the game - Say, Beta, Season 1, Season 2, Season 3, and Season 4, so that people who didn't play during those time periods can experience them. Purchases and account info would be the same across all servers - meaning that purchasing someone like Kassadin on the main server would give you him across all subservers. (If you bought someone like Yasuo on the main server, you would be able to use him on the Season 4 server but not the Season 3 or behind one.) This could also raise the amount of time players spend to unlock season-exclusive things, such as Dodge runes. Certain things like Ranked and Bot Matches wouldn't really need to be available because it draws focus away from the current game, so normal blind and normal draft would be enough. Of course, this would be incredibly difficult and costly, with the need of setting up five new servers and consistent patches of them while making new content for the main game, so I don't ever expect it to happen. I would love to re-live Season 3 and play in Season 2, though, so one can only hope.
