Hunting - Am I Doing It Right?

[LunaFaye]

I also see people shout for "invite" when certain monsters are called. Do you have to be in a party to get credit for certain hunts, kind of like the old Odin FATE?

you don't have to be in a group, however on our server A and S ranks die within 10 maybe 20 seconds. You won't get full credit if you were late or not getting enough dmg in before it dies. It's always suggested to join one of the party finder or shout groups when trying to get some seals. Most of these groups are doing more than one A or S rank, even older ones and if you're lucky you get a streak of 6 - 9 A ranks a day etc..
