I'll keep saying this - Shadowstep to HoF already. It's the epitome of mana cheating. Not a nerf, I don't know of reasons why wild can't have it as is
I prefer much more they do what they do with priest buffing some classic cards instead destroying the classes with good classic set.
Mage, rogue and druid suffer massive nerfs in your core cards over the years, this way at times goes on, all classes will turn into paladin and shaman garbage classic set.
