It's critical to be careful with buffs/nerfs. Balance needs to be fixed but if they change everything at once it'll be a big mess. They also can't only listen to those that are the loudest on things which is why I always try to be as balanced in my own comments as possible, I also don't have a 'main' so have no vested interest in anything beyond a fun and balanced experience. Player experience matters but so too does actual numerical data.
When making such changes its best to only alter a small number of things so they can watch how fewer variables affect things and then go from there. For example if they nerfed every aspect of Night Cap at once, she'd be useless.
Another factor is, what do the developers want each class to do? Do they want support characters to be more support oriented than we're used from GW1 and 2? Without them replying to our feedback with their design goals for each character individually and the categories more broadly, we can only go by what we know.
