I have not seen anything else about this, I have been looking for an answer but I can’t find any.
While I am playing I will be 100% mana. Enter combat, then I can’t cast anything because I am oom out of no where. It is something that has been happening randomly since the pre patch for dragon flight. The only thing I read a few weeks ago was someone said something about it possibly being linked to convoke the spirits, but I can not duplicate the problem. I have noticed it happen more after spec changes or shapeshifting from cat form, more specifically leaving stealth and cat form.
I am wondering if anyone else is experiencing this problem or if it is a known problem I guess.
