Why can't we change Pages and Summoner Spells inside our fountain before the match starts?
It's a really terrible feeling knowing that accidentally taking the wrong summoner spell or rune page can basically destroy an entire match, and I'm sure it's happened to all of us at least once. Considering literally NOTHING can change in that 15 seconds, why not change it then?
or
top/mid for example, you can change your runes if one of them has ignite and the other one tp.
