Yellow lets you turtle up behind your shield, debuff your enemies into impotence, and survive; or it lets you bust out the driver and hit for distance. You won't see the gigantic numbers, but the persistent Light damage on your primary target is like a big exta d.o.t. that shortens fights quite nicely.
