Hunts are pretty broken however you slice it. On a large server like Excalibur you're lucky if the mob lives for 30 seconds, due to all of the huge groups. And don't even get me started on Guildworks...

The OP has a good point - S Rank mobs die way too fast, preventing anyone who isn't in a large linkshell to participate. I don't think being in a large linkshell should be a requirement to be able to participate in a hunt, and it's pretty sad that a S Rank only lives less than a minute. The HP should be buffed to give time for more people to participate. I don't think waiting another 30-45 seconds for the mob to die is going to destroy hunts.
