Well, the dragon still doesn't have anything besides Ferrow, and it only heals for three, and doesn't put anything on the battlefield (a beast heals for 6-8 easily, better than any Haven card). Rune only recently got a healing buff, it's decent, but I'm not sure if it will be popular. Blood and Haven, yes, they know how to heal. Dungeon has Orkhus, who consumes shadows, and Flylord (if you're lucky enough to draw Drain, but the chances are slim). Considering that a couple of beasts from Fortress can almost fully heal, I still disagree; the Forest is quite good in this regard. It only got better after the expansion.
