Speaking up as a visually-impaired player, the shapes are actually quite difficult to make out because of the “holographic” nature of their display. If someone calls out the color, I do not run into any issue. However, some other players in my raid group have varying degree of color blindness and need the shape to be called out. Things get messy, but I imagine we’ll figure out a balance once the group has done the content repeatedly. Still, it would have been nice if we could avoid the messiness altogether. I would rather fight the boss than the UI.
I used to have a signature here. The Shattering… shattered it. Please don’t step on the pieces.
