Please zos, I dont wanna get disoriented looking at the crux rotating around my character. Instead, add a UI option that displays the crux above your character's health bar similar to how combo points are in world of warcraft for rogues.
"I fight because I fight. I fight for we few who fight so that all the fighting already fought hasn't been for nothing." - Ulfric Stormcloak on a typical Stormcloak rally.
When I was trying out the Arcanist, I think I saw the number of Crux you have on the buff/debuff bar (Default UI). Only issue with that, is that the numbers were rather small for me, but I would even accept having the icon change on how many Crux there are.
