I hate that crap. It needs to replace just the people who don't commence. I hate when all tanks and healers hit commence immediately, and a couple of DPS's time out, with a 24 man dungeon... and then we get another queue pop a few seconds later, but this time a couple of tanks or healers time out- most of the time, they probably aren't the same ones who had hit commence in the prior attempt as before, because those had all hit commence immediately.
