Should probably note i also run 7 choose one cards, but thats besides the point

Why would you be completing it at turn 7..? If you play the quest youd probably try to make it proc as early as possible. So youd avoid good tempo plays for the 4 early turns unless youre against aggro. But if youre token druid you still can do a lot and youd almost garuntee board pressure. I just dont see you getting the new hero power after turn 5 like ever. Ive played lucentbark druid to rank 7 this season and i usually have leftover mana early on a lot.
