Flash mode (Summoner's rift)
Apparently I had this crazy but somehow funny idea that you could have flash cooldown for 2 seconds on Summoner's Rift so that there will be flashing everywhere. (Note: Does not work on other summoner spells.) They can bring one other summoner spell but it will be on normal cooldown. This is just a fun mode for the crazy flash juke plays you can never have before, otherwise Kassadin will be OP again.
Think about it for a second.. flash I mean, 2 seconds... flash I mean... Oh well gotta keep flashing.
