To the OP: Did you not call out that the mark had spawned? Were people shouting "please wait for me, I'll be there in a sec!"? If either of these things are true then you really have no leg to stand on. If you're so impatient that you can't wait a minute or two for people who have been combing the area for Naul every single snowfall, some of them now on multiple days, to come and grab credit too, then there is nothing I can call you but selfish.

Generally: I agree that the B-rank elites need to have an increase in HP, especially if the weekly is always going to be a B-rank (though really, an A-rank already gives that many seals; I got lucky and caught the Cancer-like crab elite in Aleport), but there's really no defending grabbing an elite mark's credit all to yourself and -maybe- one or two others when you KNOW there are dozens of people who have been diligently combing the area trying to find the damn thing. I've had two run-ins with Naul today alone, plus an A-rank spawn in the East Shroud that I literally ran across the entire map for, while in a party for taking down said mark, only to discover that someone decided he couldn't be bothered to wait an extra minute and pulled it, forcing everyone else to zerg it down or lose any chance at credit. That's not in any way what the Hunt is supposed to be, it sure as hell isn't what Yoshida envisioned for this system, and it's frankly unconscionable no matter how you might try to defend it or claim anyone that criticizes you is just QQing.
