There will never be a unified front since different people want different things for the game.
For example, someone posted earlier in this thread that they wanted to get rid of normal mode raiding. For me normal mode raids was one of my favourite additions to Heavensward since it allowed me to play through the raid story as it's released unlike Coil where I didn't get past t9 until unsync became a thing.

In general I don't object to new types of content being added. I'm mostly against the restructuring of the rewards system towards horizontal progression as I don't have any interest in farming multiple sets for one job and enjoy the current pace of ilevel increases.
