"Locking In" in the new draft mode.

Why do we have to do it? Sometimes I'm indecisive about who I want to play (especially if I end up in a role I'm not 100% on) or someone makes a last second suggestion that is better than what I'm doing but when I go to change I end up dodging because I don't end up locking in on time. While I somewhat understand why it's necessary. But I feel like it ends up lengthening ques more than is needed because someone doesn't lock in one time then has to wait 6 mins to reque just to wait 20 mins to have someone dodge accidental or not. For those that feel I'm whining, this is something I've observed in a number of other people.
