Blast From the Past (Gamemode Idea)

So I have not done too much research on the new game mode coming out, but I have been thinking about my own concept for a while, and Nexus Blitz really did push me to write a thread about this. It gave me some ideas on how I think this game mode would be. Would it potentially be code intensive? Maybe. I don't really know how this stuff works, but here is my idea.

The title of this game mode would be: Blast From the Past, and its probably pretty obvious what I see for this. Personally, I really miss the pre-reworked editions of some champions. The first picks that come to my mind are , , and . There are also some great items in the game that I really wish were still there. These items include (but are not limited to): the old , the old , Devourer, Banner of Command (R.I.P), Avarice Blade, Sightstone, and many many more.

The main point of this theoretical game mode would be a typical 5v5 on Summoner's Rift, with the ability to use pre-reworked champions and items exactly how they were on their last available patch, along with their modern counterparts (champion-wise).

Now I don't know if this is even possible or a good idea, but I just miss playing some old champions and I would love the opportunity to play them again. Thanks for reading my post
