Considering the points and nuance raised...I actually think this probably tells us all we need to know about that NN interaction.
Yes, I would say it's better for them to do their job quests.
The point is you're gonna get people of all experiences and walks of life, that's a given. Ultimately, we have to be able to live together, because it's not like the devs are going to gatekeep. And for most of the time people do live together just fine and it's not a case of carrying the world all the time either. And probably why people are not seeing your objections as big of a deal as you are, yes, there are bad things within the FFXIV community, but maybe not as big that people feeling it's as dramatic as a "culture of enabling".
We can help people get better, that if anything is better for the community as a whole and people DO help each other get better, folks can good with newbies, to the inexperienced, to the people not getting it and help them on their way and if anything is why NN exists. I often try to offer people help and advice and in my 8 years in this game I've not had an experience like the one you've witnessed in NN. Where I have seen it is when somebody was an a-hole about it and the dogpiling is because that person was an a-hole about it or just rude or talked down to the player - and that's gone both ways too, if the person being given the advice is just an a-hole about it, I've seen people dogpile on them - like "you don't pay my sub" guy I mentioned in a previous post, we ended up kicking him.
Given this is a point raised that you're dismissing it in a sweeping "This is what you people defend" then it tells me that maybe it's an accurate point.
Sure, there's a handful of bad responses I get from individuals, oh well, there's some people in the world who can't take it. Move onto the next one. It's not common enough for me to be like "community is bad".
