It only grants you 1% more if you burn the second bar which hardly seems worth it unless your opponent is at very end of there life bar. However if you have war-banner out the further amplified move now grants you 2% more which seems reasonable considering that someone like liu kangs extended bicycle kick only has 2% more also. Only big difference is that liu doesnt need a buff-damage out where as baraka does. Honestly i get salty over stuff like this considering that liu kang is top tier with god like tools that make him good but when they decide to make baraka he has a flaw that puts him behind even further over a simple special move that should be equal to liu kangs.... just saying..
