I'm going to also second this suggestion, as someone not even having a 4kHD display. (Dell 30" @ 2560x1600)


Some of us are visually impaired. The larger that we can make UI elements such as the compass, HP bars, skill-bars, etc, the easier it is for us to play the game. Please just consider permitting UI elements to be scaled to a custom "user-input" size.

--For instance, if I could make the compass 400%+ scale, I probably would. Point is that this isn't something that effects just a niche of the market of people playing on high end rigs with expensive monitors, it's also an accessibility feature.
