UPDATE - Nerf em quest da staff lendária - droprate de "Smoldering Essence" diminuiu

A Blizzard não quer popularizar as armas lendárias, eles querem manter as Lendárias como lendárias como diz o blue post abaixo.
Estão tomando medidas o quanto antes para que ela não seja disponibilizada tão rapidamente.

We didn't particularly want a lot of these items in circulation, so that's partially intended. We really do want to keep legendary weapons legendary, and Dragonwrath ended up being more readily available than we were comfortable with.

Nonetheless, we should have recognized that the completion rate was faster than we wanted, and taken action, sooner.
