Can we have a visual indicator for Nasus's Spirit Fire and Renekton's Dice?

It's always bothered me that there's not much clarity for these two spells that provide a fuck-ton of hidden utility.

For those of you that don't know, Nasus's Spirit Fire slowly reduces the Armor of enemies standing in the circle, and Renekton's Dice instantly reduces the Armor of every enemy it hits.

However, neither spell provides a visual indicator to show that you've been tagged by either of these spells. Yes, it does provide one on the debuff indicator, but Black Cleaver provides both, making it much easier to tell that you're still under the spell's effects.

There are many abilities that provide an indicator like this, and I personally just think it would be much more beneficial for both the Nasus/Renekton player and for their victim if they could see that they're still debuffed without having to look at their debuff bar, or in the user's case click on their enemy.
