“We” as in Blizzard developers? Or “We” as in the Activision-Blizzard accountants responsible for making financially viable decisions? I’m honest-to-god not being contentious here, but it seems so far the financial viability of Classic would hinge upon getting folks to play it, and having the reward structure go from Classic->current would support that financial viability.
Refer to my post above- I really would play Classic, for years, if there was a guaranteed way to get the Black Scarab mount as an end goal. I wouldn’t be able to play BfA for years, nor would I want to.
