More Time After Lock In? (Blind Pick)
I believe that it is physically impossible to create an entire new rune set in just the given time after locking in a champ. I have gone multiple games with wrong runes simply because i made a last second switch to my champ before locking in. I then nearly or actually complete my new runes page before the game starts but I almost Never have enough time to save it. All I ask is for five more seconds added before the game starts after everyone locks in (yes I believe it will make a difference). Obviously this is only really applicable to Blind matches given that you're normally waiting on other players to lock in after you do in other ques.
I main supports so sometimes I'm stuck with support runes as an assassin jungle which obviously doens't pan out well. So runes actually do make a bigger difference than some people might think, especially since the major rework. It's obviously not the biggest or most common of problems but it's an easy fix to a problem that lasts all game.
Note: My champ pool is Very wide so two pages of potential preset runes doesn't help me,. Even if i bought more I'd need like ten pages which is more BE than I've probably ever earned. (Even with a known rune set in mind i just cant click fast enough and sometimes it doesn't even register on the first click.)
