Fury of the Faithful gives you +20% attack speed, Martyrdom gives you +28%, and the attack speed node that leads to Martyrdom also gives you +10%. A total of +58% attack speed is fucking insane. People love Weapon Specialist on Veteran because it gives you +25% attack speed in total, but think about having over double that, in a class with even more melee damage. And yet almost no Zealot dares do it. Martyrdom's toughness damage reduction gives you tankiness equal to three flat +17% toughness curios, at 7 wounds.
