Best game mode conceived
I think that veterans would really appreciate this concept and even new players.
There needs to be a game mode that allows you to play champions that have been reworked in thier or original form within modern map/itimizations (or maybe even include old items). For champions that have been reworked several times such as ryze let the player select ryze1 ryze2 ryze3.
I understand that the original data for these champs has been overwritten or lost but I imagine it wouldn't be too hard of an undertaking to recreate these kits given the content that riot has demonstrated.
I hate new game modes and only play them for missions. I never even got in to urf. However if I could play original rengar, galio, quinn, and so many others; I would play this mode every second it is live. It's a celebration of riot history, a celebration of what was fun/broke, a damn good time.
