New gamemode idea

Ok i was just thinking about old league of legends like s3 and s4 and because i started in the s5 to play league of legends i never got to experience the OLD champions like the old fiora or the old sion tf and those kinds of champion so i was thinking what if Riot made a gamemode that has these OLD champions in them so the newer players could experience how League of Legends used to be like. Those are just mine thought is you do it it would be awesome and if you dont its ok. <3
