Champion uniqueness

The last few champions have been fairly unique, or at least have some element that identifies them. If I were to describe a champ as able to burrow underground, I could only be talking about . If I were to describe a champion that was bound to an ally and had special interactions with that ally that they didn't have with other allies, I would clearly be talking about . A champion with a ground targeted AoE shield that allowed champions to dash to them: .

Now for an example that I feel don't fit this. A champ with a skill shot q that if it hits can be reactivated to dash to the target: or . A champ that can dash to an allied unit: and half of those can use the same ability to jump to an enemy for damage. A champ with a knock back ult that affects enemies near the target: . What I'm trying to say is, I don't know who lee sin is/what makes him lee sin(within his kit).

Are there any other champs that you feel like don't feel unique and why? Is this a problem?
