maybe the cange to arctic armor is the problem because now it´s like an aura with a mana reserve. we need to wait wat pushedx says about it
my setup of 2 heralds + 1 aura didn't cast correctly too. Only casted 2 of them and didn't even try to cast the 3rd one (also it seem to ignore the auras which are not on the panel, requiring a slot per aura now?)
I need full logs in a Support thread if you have an issue. I tested with one aura and one herald and didn't come across any issues before. The CR did not change in terms of auras that require slots. It's the same old routine as before, just FYI.
