I think this is a good change to the card. In life, you get 5hp a turn, in light you can use sanctuary for 4hp + protection from some spells, and in everything else you get 4hp/turn. Before dropping it by 1hp, I think it overshadowed sanctuary in a lot of decks. It'll be tough for me to decide now whether to use the 4hp SoG or sanctuary in my fg farmer. Right now I have a split between them.
