New Gamemode Idea

Hey, I think it would be really cool if you could make a gamemode that featured some of the older seasons, such as seasons 1, 2 and 3. You could bring back the old map, items, champions changes, etc and would be able to play in it. Whenever I see the old Summoner's Rift, it makes me remember how much I loved season 3. I think it would also be a great experience for newer players, so they could see what League was like a few years ago. Give me some feedback in the comments and tell me what you think. :)
