some rough suggestions
So you ask for less clutter with names and then add 30 more things to clutter the screen. No thanks. The currency suggestion just boggles me as its just 2 clicks away and would put like 20 things on your screen at once.
Those other GUI (graphical user interface) things would have an option to enable or disable them. The rank and profession symbols would make the in-game screen less cluttery when there is a large group of players on screen. For players who want full game status info for ease of playing, usefulness and qol this would be very helpful. Call it an advance gui if you will. A basic gui implemented could also be more useful for the minimalists too.
I do agree that there should be less name clutter, especially enemies in wvw as hiding behind a corner doesn’t really help when you’ve got a big name hovering over your head. As for the others, that’s personal preference
