In normals, why even bother locking in in the first place? Literally the only reason you lock in is auto/insta-locking so that nobody else can take your lane without even calling, and that's it, even though people have already called it first. And even if the original lane caller is persistent in wanting his lane back, the 4 excuses you'll hear from that auto/instalocker jerk are:
"I connected too slow, stop blaming me lawl"
"I called it first dude." Proceeds to copy/edit/paste the chat
"Premades, stfu"
"I watched this in LCS and I wanna be an LCS-wannabe retard, so stfu and lemme instalock lolol"
I suggest Riot to just remove the Lock In bar altogether to end these frustration, and let the champion select be over in 1+ minute as usual. There, no more "Oh fuck, wrong masteries/runes/summoner spells" or "Oh fuck, wrong skin!".
