What if Ardent Censor was split into 2 items
First item is basically ardent censor without the current third passive effect. Perhaps riot could change that to healing/shielding an ally gives both of you +20% movement speed for 1 seconds. Basically you both get a little boost in positioning if used right. For the second item, take the second bonus of on-hit damage and AS boost from the current ardent and put it there.

and make it a nashors lite for supports to grab.
So you are probably asking why two items.
Well that's simple, cost and item slots. Make supports have to choose what they want.
