so it turns out that contrary to popular belief, everything doesn't follow a super strict rigid schedule of "X always happens Y weeks after Z"

This is the first time they've had this long on the Savage delay.

It's a good compromise. Means the normal patch schedule isn't delayed but also avoids Savage release over a major holiday. It's late enough the devs can enjoy New Year's. And we get a few more weeks to obtain tome gear and run the new EX for weapons and such.
