Cap the Righteous Fury of your players. Oh god, cap it. I have had a Hive Tyrant taken out to Kraken Bolts due to the first 2 having: Bolt 1 - 7 Righteous Furies, Bolt 2 - 5 Righteous Furies.
I would say cap the Righteous Fury at 3 and spend a Fate Point to add one more. Thus making it easier for the enemies to actually....get a chance to swing if they are Masters.
