They don’t need to take up much of the screen but I do think they should be the most prominent part of the hud, aka the first thing that catches your eye when you look down at it. Currently, for me, that would be the center where the level and dodge is. I’ve seen some gripes with the spike in the center and I don’t necessarily agree with those, I think that part is fine as is. But, in my opinion, the orbs should be at least the same height as the spike. i’ve included some huds from different arpgs all with the orbs as the most prominent part and GD’s for comparison.
Stylistically, I enjoy GD’s the most. They knocked it out of the park. And in the end, if they choose to keep them as is, I’m not going to lose any sleep over it. But I do think increasing the orbs just a bit would help them catch the eye a little more.
