There are soooo many other Mythical not dropping issues, One would think that they would do something about it. Does not seem so :+(
Like many other, I am ready to rage quit the game because of this. Oh so many of the boss farming, pits, articifer and basically everything and everywhere and not one single mythical.
I randomly had a spark in my inventory and suddenly was equipped with a mythical chest piece, but that is all I have seen.
What is the point of buying the expansion pack at this point? So I can grind many hours a day to get nothing? Walk thru tormented bosses to just get basic ancestral gear, typically 0 star, the odd 1 star unique? All go to salvage anyway.
