A Helpful Change to Editing Rune Pages in Champion Select
tl;dr If you forgot to select a rune/ save your page in champ select, the game will use your unsaved runes (then they will change back after the game) or choose a recommended/random slot (or keystone).
In the 8.14 patch notes under the 'Champ Select' category it says:
> It’s a bit harsh to break up a champ select lobby on a missed ban selection, so instead, failing to ban a champion will default to “No Ban” and champ select will keep on truckin’.
We could use this (kinda) for the runes in champion select. I queued for a game of ARAM, I was setting my runes and I forgot to set one slot. So instead of going Predator Warwick I went Aftershock Warwick. I was hyped up to go soaring through the map with my ultimate and Predator until I saw my true runes. I thought that the game should just choose a random rune in the empty slot because Runes Reforged can make or break a game. Then i thought that if you forget to save the game should use those runes for that game only. After you see that juicy victory screen, your rune page would change back to your last saved runes. So if I change Electrocute to Guardian, I would play with the Guardian rune but after the game it will revert back to Electrocute. I thought this would be pretty neat idk.. anyways have a nice day :D
