I was kinda afraid that 5% reduction would be too much to be honest, considering that the ultimate also deals decent damage. At most I would buff that reduction to 6 or 7%.

Don't forget that the shield blocks "physical damage" 3 times, spells are included, not just basic attacks, and while applying that shield to your ally blocks some AD, that shield and armor boost meant nothing to the opposing AP who can just burst you down, the shield does not stop any opposing CC either. It's just meant a certain amount of protection to one of your valuable allies.
