Argument is usually coming from the miss-match of the point of view. If wait 30 seconds can make another 50 people also earn the credit -> 50 more happy people, "I" will be very glad to do so. "I" will shout for the mob's location and share the credit with everybody. Most of people in our server have this sharing thought in their mind. I'm so happy I'm together with a big happy family. "I" also sort of understand why the people want to pull early or solo it. One day when I was mining some lv25 stones for my pond crafting, I got hit by one mob (later I knew it's B rank). So, I changed my job wait for the cool down wear and hit him back. Then, there was one person was mad at me for didn't shout the location while she hit the mob with me at mob's 30% hp, that's like 8 mins away since the mob hit me already. I always heard about the teamspeak team but never know how to reach them even though I tried to ask people in various LS and no one answered. I was so upset because it's only 5 seals, the only NM I saw in 2 weeks and I already made people mad... That event made me don't want to do ANY hunt forever.
Fortunately, one day super Vergil saved me and invited me to a hunt party, (aww now it's like I'm preaching

) then I met lots lots really nice and kind people. It's like my hopeless I-will-never-get-any-allied-seals thought suddenly like thunder storm -> clear or hmm 5:59am ET -> 6:00am ET (super music starts in Eorzea) happy happy time. People are nice in there keep repeat and repeat location and where need to be careful, or "please be nice to the early puller". It feels nice since lots "orange" names around me and I can stalk them at once.

I can now team up with Mr. Face, team up with the random stranger I kept seeing jumping round market board, team up with the Roe always show up near retainer bell with super whm robe, team up with the person always stand next to Grid Crystal, and get to know all of them. It's really a nice event that very fortunately I was inside one nice server that has people willing to band together instead of "It's my precious!" and fight each other.
