Allow us to choose a pre-built rune page if we end up unable to save our rune page before a game beg

It is absolutely infuriating to end up having a useless rune page when a game starts because you thought you had enough time to edit your rune pages so you don't go aftershock Shyvana. I understand that Riot wants to make money from rune pages, but I've had countless games where I, or someone else on my team (or even the enemy team) failed to edit their rune pages in time and end up with something awful.
