You can make any champion sound op if you just list out what they can do
I have a long range attack, I can dash EVERYTIME I auto attack, I have a moving ward, I can do tons of damage to tanks with the click of a button, and I can protect my friend from harm or use them as an engage, knocking everyone up who they hit.

The more you damage my teammates the more I heal them. My 2 damaging abilities have low cooldowns and aren't even skillshots! My main damaging ability has the ability to shred armor and this stacks. 10. Times. It also reduces the cooldown of my heal by a lot. My heal heals so much and gives 110 armor! I have the ability to give mana for free and silence an enemy instantly with no cost at all. My ultimate heals every ally on the map so much.
