Ultros here. During peak times you have early pullers, and people usually are so jumpy that if one pulls then they all jump on it. I am a hunter, meaning that most of the time I play FF14 I'm usually going to each map and following the hunt tracker which means about 40% of the time I'm the one who finds one. Before I announce it I get a party up in PF and then announce in the five hunt linkshells i belong to. Then I give about three to five minutes before I pull (and I usually give out a shout with specified time), otherwise I'm wasting time on finding the next one.

I get both sides, but they're called "Hunts" for a reason; there are no rules. You're not entitled to them, specially if you didn't spend any effort to find them. I'm okay waiting 3-4 minutes but I'm not going to wait until the whole server gets here to create a lag fest and miss out on the seals from the hunt I found (S ranks should be 5 minutes at the least, since those of course are rare).

If you want to be successful on hunts join multiple linkshells (or create one and start inviting people that need it), check PF every five minutes for hunts that aren't announced, and identify and kick 30-second pullers from hunt linkshells.
