Common Sensed Champion Ability Add-ons

I wanted to make a thread based on the communities opinion about any champion who seems like they should have something, but actually don't. I feel Riot can bring a lot of realism to a lot of their champs if they add on certain effects that express the champion. For example, I'll start off with Elise. Her Q in Human form Neurotoxin expresses her value as a venom filled spider. But wouldn't you think she would have a DoT poison on either her Q or W in Human form, or even her Q in Spider Form? I understand if you get the enemy low enough you can rappel to them, but if it's on cooldown, you could really miss that kill that helps the team. Another champion would be Zilean, he is commonly found on the support role, and yet, a strong Mid Laner as well. But what if his W-Rewind was used for either/or Speeding up and "rewinding" damage taken recently. (Healing) And when cast upon an enemy, could damage them and slow them. Spamming the bombs is his most distinct trait, but I think he could be expanded upon more. I have more ideas but I don't want to make too big of a post.
