Regarding the Wild Growth change

In the past few weeks out of all the decks using wild cards I never saw it used. I’ve only seen it used in mono green where forest counts mater. In the wild decks they just used Earth craft and Elementals because nothing important really happens until turn four where they easily already have six colored lands. Wild Growth was not needed at all.

My only guess is its a nerf to mono green or a nerf in expectation of new cards or in expectation of a wild nerf requiring more wild lands on the cards.
