Confusing look of crystals in Energon Store

Beniamin

Why these crystals are so similar?
Three of them are blue, three of them are different.
I almost bought booster pack thinking that one of the crystals it's 3* bot crystal. It looks like 3* bot crystal. But it's not.
They should change the look of crystals, because it's too similar to each other.

If you tap the pic of the crystal it will tell you what kind of crystal it is.

I know. But to be clear each crystal should be characteristic.
