I'm currently catching up on Head Designer Mark Rosewater's "Drive to Work" podcast. I've been out of the loop for about a year.
In Episode 460: Announcements, which aired in August of 2017, he says:
"There is a big revamp in behind the scenes of how we make Magic. A big one. Like, probably the biggest we’ve had since I have worked at Wizards."
He goes on to say that he will write an article in the fall to announce it, and that it's "the biggest change we've ever made."
Well, fall has come and gone and I'm still clueless. I've perused MaRo's articles from August through now, but I still haven't found anything that indicates or announces any sort of major paradigm shift.
What is the big change MaRo is referring to? And, if possible, What articles/podcasts cover this announcement?
