I see no harm in a 5-7 minute window. It basically changes nothing except for early pulling, and while that's well within the rules, it's anti-social and not like catering to that type of player (who is less than 1% of the hunt community) is important. I really couldn't care less if early pullers and griefers are upset over a 5 minute wait. It's no loss. They've been using "but the rules allow it!" as an excuse to enjoy seeing other people upset for years.
Hunts have evolved from the initial intended purpose. They're community coordinated now and the devs can either choose to remove or rework the entire system, or embrace what it's become and improve it. But pretending it's still a small scale activity for whoever was in the zone at the time is being delusional. Especially when you create multiple "kill 1000 S rank" achievements or SS ranks.
