Heralding a new age where they realize the current state of CF is for the best.
Goblins and frost becoming regular is hardly a big change.
Frosts don't differ enough from fire that this change is meaningful, and goblins suck so very much when you play them, fun as they can be for non-serious players.
Unless goblins can now go to 51, and have been otherwise revamped.
Scar's just one man, would be hard to imagine him recoding a bunch of shit for a new age, but these things were probably pretty easy and give the appearance of change.
Just give people Entropy, Shadow and Master back.
I never played when those existed, but absent something like that where Thera would actually feel very different, this change doesn't inspire me in the least to want to play CF again.
But maybe something interesting will come about that makes some people that don't play want to once more.
