Choose the patch you want to play on in custom games.

Now I know this is a bit far-fetched and would need a bit too much effort but think about how cool it would be to be able to play AP , AP or just pre-rework champions like old , old or 1 of the many forms of against your friends or in a custom game with randoms with the indication of which patch the game would be running.

By the way, not only old champions would be there, also other things like removed items such as Deathfire Grasp, Force of Nature and many others.

The old graphics of specific patches shouldn't be included however since that would take up way too much space on your internal memory storage for just a downgrade of graphics (in my opinion).

Let me know what you think about the idea, dunno whether this will get further than an idea though.. =O
