Honestly, you could remove "Influence followers" from priests, and it wouldn't be a nerf. Heck, it'd be a boon. That action sucks at everything else than sabotaging your own religion. The more "advanced" you get access to, the worse it gets.
A senior priest with 100 oratory fame can't cause more harm to a region than what it can naturally recover by itself at TC. He can't fix a region any more quickly than a newbie courtier who just started out. He can't increase or decrease sympathy any more than a newbie diplomat. The deaths from his mobs will likely go unnoticed and will undo themselves within days.
It's an awful ability.
By the way, Alaster is dead, so SA is now somewhat "unsurped". It can now return on its slow path to death.
