I feel the same way, even on Balmung. My FC only has about 6 people online max at any given time, and when they are on, with the exception of a couple of people I feel like I'm completely ignored.

I'm not too concerned with people chatting in dungeons though. The fact that you probably won't ever see them again and SE designed things to not allow you to communicate cross server sort of discourages people from bothering talking there.

I know your pain though :/ it sucks
