You know, the Yasuo rework wouldn't be bad as a game mode.
Or hell, make it URF 2.0.
Instead of giving everyone free resources, super high mana costs, etc? Just buff up everyone to stupidly high degrees by giving them new aspects to their existing kit.
The Yasuo rework joke had:
- CC/Spell vamp immunity
- Triple tornado after the first hit.
- Wind box.
- Ward hopping
- Infinite ult.
Now imagine you gave such a thing to every champion? As an example:

- Passive instantly procs.
- Q passes through all units.
- Can now leap to wards and enemies.
- Shield now absorbs all projectiles, massive wall increase
- R extends WAY further and knocks everyone up.
Sure, it'd take forever to make. Yes, it'd be broken. But fuck if it wouldn't be entertaining.
