I agree with the with the lack of community tools. I also don't understand why the game doesn't have a general chat channel. Somewhere when you can go "Yeah, I'd like to do that, is anyone up?" on the fly. Novice Network is kinda used for that, but that's limited to 512 people at the same time, and you need to be either a novice or a mentor. When I look at it, it's often useless conversation, but that's part of what makes a mmo live. On other mmo, I sometimes spent hours on debate about lore points there with people I never met. Here, despite the community oriented posture, everything is done so we only play with people of our FC.
I have nothing against the Duty and Party Finders (For playing mmo where there was none of those, I can tell you they're a good thing, that help to keep all), but they're both kinda impersonnal. Plus they ask for an active search, you can never just see a message and go "Oh, yeah, it's been a long time I haven't done that, why not". You join, some say hello, and that's it. Having the possibility to just use a chan to discuss and make team the old way would be a nice touch. Interacting with the people before going into the content help making the mood of the party good, while right now, everything is done so you don't interact with other player.
That's one of the strong points of Eureka and Bozja content. Those instance were probably the ones that felt the most mmo, people are mostly chill. In Eureka the norm is to ask if there are people on the way before starting a Fate. In the rest of the game, it's rushing and everyone for themselves. I think part of the reason why it's like this is that it force you actively search for a party the old way (with the fact they had interesting drops and reason to run them on the long term), being forced to interact with them, and actually feeling mmo (I feel like that might also be why people miss that kind of content so much). Right now, this game is in a state where they say they're proud of their community, but do everything so their community doesn't interact with each other. Everything is designed so you don't do circumstancials party, because it's not pushed.
