The Beledar oil is clearly the one meant for healers to want and use, but it underperforms compared to the Algari Mana Oil because it doesn’t proc enough (and it requires one profaned tinderbox per 5-stack), so like Teishoku said, they don’t need to change the mat requirements for mana oil. They need to buff the other oils to a state of competitive use so that supply and demand work as they so clearly intended but didn’t deliver on.
