I want to craft Living Roots(not have before) but it is now epic and I can not afford epic dust value. I will NOT PREORDER new expansion because Hs Team made changes secretly. If It is a bug, why not other common cards became epic and only Living Roots is epic now. 

 It IS a bug and confirmed as a bug. Your conspiracy theory makes less sense than the real explanation. 

Yeah they're not gonna punish the few people that got to take advantage of this as it's not worth tracking those people to begin with. The gain is so minor and it's not like you were able to exploit it that easily since you couldn't craft the card before the change went live with the knowledge of profit. 

I can't think of a scenario where the rarity on a living roots matters though. It's oddly specific for them to change just the rarity on a card that isn't even in standard anymore.

We assume it's a bug because there is zero reason to do it intentionally. It makes no actual sense. 

This seems so unintentional to me. There's absolutely zero reason I can think of that would explain them choosing to do this.
