Small needed improvement on rune VFX Font of Life

I know this is minor but can there be an improvement on the Font of Life rune VFX? The green icon just hovers on the enemy champion, but allies attack it and it just sits there with no effect, as if nothings happened. It'd be awesome and I feel like it'd be used a lot more in synergy with ardent censor if there was a clear visual effect of the green icon being consumed and healed for.
