Hello zenimax,
I am exploring tanking with the new arcanist now which I like quite a lot so far.
Though I would be happy to see an improvement with the the crux count to make it more easily readable. The icone in the list of buff/debuff doesn't stand out from the tons of effects on me. The number is a white number on a light green triangle, which makes it hard to read.
People that don't want to use addons (or, like me, can't because of console limitation) may also have a harder time to count crux while a bunch of visibility nuisance are on screen. Sets like maw the infernal, colusus ultimate, trees... subtitles are sometime in the way too.
Hopefully this issue is significant enough to be taken into a qol meeting someday :-)
Otherwise, i'll just lean to deal with it.
Thanks for reading.
