Some people doesn't want to waste time helping other people out. Hence the experience needed PFs.. In contrast to the Japanese servers where majority of the players are willing to people help out each other. There was a video of an ffxiv podcast about this

I'm not saying NA/EU doesn't like to help people out, there are a couple of people who jumps in learning parties with a clear. But most players want to clear it because probably all their previous pf parties wasted too much time that made them block out inexperienced people

But there are some who avoid helping out like a plague because there are some (a lot) of newbies who just expected to be carried. In my server and I know someone who calls these as trap parties lol

Good thing you can do is ask your FC to help out and most of the time they're willing to form a group because of the bonus. Best thing is to form a static. Because honestly, you won't progress content as much as you think with just PF and DF.
