I do not see the baseline of FFXIV being easy as a bad thing as it helps to draw in as many new people as it can and not proceed to beat you up for just trying to do the story. Just look at Wildstar as an example of catering too much to harder content.

However i think they could add more midcore content ie challenging versions of existing dungeons if they ever get a manpower boost or a potential boss rush for glam rewards, but i want to stress this should not come at the cost of the already existing content structure.

As for communication as much as people hate it Eureka actually had a lot of it and not just lfg fate XD it got really active with the introduction of Baldesion Arsenal and new discords were popping up to try to clear it, he community is there it is just a case of finding it or finding something that will bring it out.
