I'm honestly surprised that this wasn't already on the radar. ARAM has been around for many years, and this is an annoyance every ARAM player will experience, and the solution is pretty obvious and straight forward. I know it's not a big deal, but beyond that is there some reason it never got brought up before?
Game dev is a long and complex process, especially when our game is updated extremely often. 2 weeks may sound like a lot, but it needs to run though various teams like QA, Localization, etc before we can even consider shipping it to players. Because of that our structure needs to be very, very rigid. We have to plan all of our products fairly far in advance in order to not only maintain our normal patch cadence and update cycle, but also implement new products (like new champions, reworks, item updates, etc). The reality is these types of changes need to be discussed and we need to make sure they are right for the game because we proceed, because no matter how small a change might seem or how much of an easy win it appears to be, we can't just ship it willy nilly. Even just having these discussions is a certain time cost, and so its never just as easy as thinking up a change that seems popular and proceeding with it.
