Master Yi's kit is surprisingly deep and well designed

His Passive - Double Strike is unique and interesting, not to mention a delayed form of power that's simple to understand by anybody. His Q - Alpha Strike acts as both his gap closer as a melee champion and primary defensive tool as a skirmisher - a surprisingly deep ability defeated only by Master Yi's reputation as a noob stomper. W - Meditate is also a funny ability, temporarily turning Yi into a wall that can't hit back, so unlike certain Gameplay memes of being an unkillable wall that destroys squishies, Master Yi must choose between defending or attacking. That and also the Auto Attack reset built into it, adding a different angle of balancing defense for offense. All of these abilities are surprisingly deep abilities for the simplicity that they offer.

Of course this falls short really quickly with his E - Wuju Style and his R - Highlander. You can see some semblance of the depth his other abilities have in how he loses his passive AD on his E if it's on cooldown, but unless it's something more akin to Kled - a really quick burst of power and a downtime that may happen in the middle of combat - it's really just a literally free steroid. Literally, no mana cost, not the League playerbase's version of free that is "I flashed them under tower and got a kill for free".

If Yi ever gets reworked, I highly expect it to be a Gangplank or even Tristana tier rework, where they focus primarily on one huge change in the champion's kit but leave everything else (retuned but) more or less the same.

Now if only they fixed all of Yi's weird bugs.
