An idea that will probably get downvoted.

Something I don't like about the different dragons is that it is really easy to see the effect of Air and Water dragons but it is hard to see the effect of Fire and Earth dragons. To me it feels like Earth and Fire dragons are hidden power so this idea is to make the effect of these two dragons more visible.

Fire: After 1 second of not damaging the enemy champion the effect of the fire dragon will kick in and deplete the enemy's health further. Think of this as a mini zed ult instead of just having the extra damage stacking on top of your already existing damage. This way you can see how much extra damage the fire dragon applies to enemy champions.

Earth: After 1 second of not damaging the enemy turret the effect of the earth dragon will kick in and deplete the turret's health further. Think of this as a mini zed ult instead of just having the extra damage stacking on top of the damage you already did to the turret. This way you can see how much extra damage the earth dragon did to the turret.
