As you know, there's a new champ select method, but everyone know that.
In the old method, if u picked a champ, u didn't have to press LOCK IN, just click on the champ. In the new select you HAVE TO click on the LOCK IN logo... I think its a kinda annoying, because if someone forgot to click on that, he will be kicked out of the queue. I think riot should remove the lock in, because so many people will lose LP because of this.
