Banner of Strength gives +170 Power but Frost Spirit gives +10% damage
Bowl of Sweet and Spicy Butternut Squash Soup gives +100 Power but Bowl of Seaweed Salad gives +5% damage
Revealed Training gives +200 Power but Symbolic Avenger gives +10% damage
What would happen if they removed all percentage based damage boosts from the game and replace them with flat bonuses to Power?
That way the top damage builds will deal less damage, while the lower damage builds will see a slight increase.
By making them give a flat damage bonus they will be abilities that offer the same benefit regardless of the build they are used on.
