Even if it's not a need, there's so many things that would benefit literally everyone playing the game. A small QoL update like adding timers to the buffs and such displayed on the party list alone would help tremendously, for example. Things like chat bubbles would be great for RPers and people taking funny screenshots, and wouldn't bother anyone especially if there were an option to toggle them on and off. Being able to change the colors of various markers such as AOE puddles would help a lot on troublesome visual fights like P3S.

A lot of small things can go a long way. And if you don't want them, you don't have to use them. But there's always benefits to more options, accessibility, etc.
