I don't think the nerf to ancient of lore is as bad as some see it. A 5/5 body and draw a card is decent enough in the late game to keep you going.
Druid will be playing tons of large creatures now so you basically get another turn out of it.
I think it will still see play.
It's definitely bad. A 5/5 body isn't terrible in and of itself, but at 7 mana you are giving up too much presence in a class with crap removal. 2 cards were absolutely worth that risk, 1 card is probably not. I also disagree with the notion that a)it automatically made its way into every popular deck, because it didn't and b) it had as much of an effect in games as people think it had.
Maybe that's what it's missing. Give it +1 spell damage.
It's missing something. It's too big of a nerf for a card that absolutely needs to be strong.
