Make Relic Shield speed up the attack frame to a set value

You wanna know why no one lets you CS using Relic line late game?

Because the gold distribution sucks.

Gold from the execute is given to the target closest to the champion with the Relic line, and when you're grouped and you're all trying to CS the lane, you (the carry more than likely) want the gold, but the front line tank/bruiser will be sitting closest to the support. So while the support sees it as "wow y u no let me proc" the ADC/midlaner wants the gold to finish off a vital item.

So speeding up the frame won't do much because the problem lies within the selfishness of the carry role.
