well. Unranked has become a living hell right now, I'm not having fun anymore
Just play ranked. You can't rank down and you find a wider variety of opponents. Down the line, you get a golden hero when you played 400 games with a certain hero, later down the line. Unranked is harder imo, since you get paired against equal or better decks (most likely), where as in ranked you can face anything.
edit:
I have 1k dust again. A few more arenas and I can probably craft another legendary. But which? Thinking about Sylvannas or Thalnos, but I find the latter to be not much practical for my warlock deck and Sylvannas is a bit slow. Mhh.
