Supports don't feel fulfilling because you can't see their effects

I remember a few years ago riot said they wanted to remove invisible power from the game, but a couple of support abilities have no visual cues.

Bond of stone has no visuals to go with it. When I dazzle the enemy adc and mark it with bond of stone how do I know my allies are being healed? Do they know they are being healed?

Also, emperor's fervor has no visual effects to it. How do my allies know they are moving faster towards me?

I know LoL has a bunch of visual clutter, but make supporter seem a bit cooler by showing players what their skills do.
