There’s nothing more kingly than being carted around in a litter, so August tried a kit similar to Yuumi’s.
Viego attached to an ally and followed them around the map, leaping out and attacking enemies whenever the opportunity struck. As fun as that design was, it didn’t feel like a king. He was bound to the whims of whoever he was attached to, incapable of commanding them to do his bidding.
If Riot was looking to make League's Big Bad, I can't imagine something more horrific than the concept of "assassin Yuumi".
Thank god they decided not to make that his kit.
Edit: Honestly kind of impressive how many ideas this Champion Insight talks about regarding scrapped kits. We get Assassin Yuumi, Full Rift Mist effect (Camo and spawning an army), starting with a broken blade of the ruined king that upgrades over the game. I love hearing about the scrapped kits and hope that more of beta kits are shared in the future.
