Master Yi needs a big change rework because the binary run at you gameplay is not fun to go against nor does it offer any skill expression for each player to decide how they want to play as Yi. Skill expression is the choice of how you want to play a champion and adapting your play style based on the situation, it is not an indication of something requiring skill or not.

For me, I want to see Master Yi as an ability power swordsman to grant an unique gameplay. One that is patient, lays in wait for the perfect opportunity to go in, and then swiftly finish off the low health stragglers! I want Master Yi feel fair to go against and that he "deserves" his kills, rather than getting fed and pressing R and mindlessly running at you with hands off the mouse and keyboard, being broken may be fun for the player, but it is not interesting at all and not fun to go against (do not confuse being broken and overpowered as the same thing; Yasuo is similar to this as well).

Very important here, I want to make Master Yi feels unique and give him something that only he has and make him different to other assassins, this also helps with giving him some kind of fallback team utility so he does not need to be feast or famine.

Meditation (Passive):

When Master Yi stands still for 1.5 seconds without performing other actions, he begins to Meditate, healing for 2 - 10 (+5%AP) health per half-second. Master Yi glows brilliantly orange when standing still for 3 seconds, increasing how much he heals to 8 - 40 (+20%AP) health per half-second.

Disruptive crowd control will interrupt Meditation.

Alpha Strike (Q):

Cooldown: 10/9/8/7/6 seconds; Cost: 70/80/90/100/110 mana; Range: 500 / 1000 / 1500 units

Master Yi dashes in the target direction, dealing 40/60/80/100/120(+75%AD)(+50%AP) physical damage to enemies he pass through.

If cast while Meditating, then he summons a spirit that dashes with him and travels 500 range further, dealing 40/60/80/100/120(+50%AP) magic damage to struck enemies.

If cast from empowered Meditation, then he summons an additional spirit that dashes with him and travels 1000 range further, dealing 40/60/80/100/120(+50%AP) magic damage to struck enemies. Enemies struck by this spirit and were below 6/7/8/9/10%(+1% per 100AP) health are executed, refunding Alpha Strike's cost and Steadfast Warrior's cooldown.

Steadfast Warrior (W):

Cooldown: 13/12/11/10/9 seconds; Cost: 50 mana

Master Yi refunds Alpha Strike's cooldown and channels in place for 3 seconds, gaining crowd control immunity and 40/50/60/70/80% damage reduction from all sources while channeling. Casting Steadfast Warrior does not disrupt Meditation.

Casting another ability will end this channel.

For the next 3 seconds when the channel ends, enemies struck by Alpha Strike will have all of their shields destroyed before its damage is applied.

Wuju Style (E):

Cooldown: 8 seconds; Cost: 45/50/55/60/65 mana; Range: 1000 units / 75 degrees

Passive: Wuju Style's base cooldown is reduced based on bonus attack speed that Master Yi acquires from items, up to a maximum of 4 seconds reduction in this way.

Active: Master Yi's next basic attack attacks twice, dealing 30/35/40/45/50% damage on the second strike and causing both attacks to deal magic damage, each strike applies on hit effects in full and deals 20/30/40/50/60(+30%AP) bonus magic damage on hit.

If Master Yi was Meditating, then he slashes twice in the target direction instead, varying in power based on his current power of Meditation and then returning him to a full power Meditation afterwards. The first slash is in a line and the second slash is in a cone, both slashes dealing 50% increased damage when empowered.

Ancient Tree (R):

Cooldown: 110/85/60 seconds; Cost: 100 mana; Range: 1000 units

Master Yi calls upon a cherry blossom tree of old from his location for the next 5/6/7 seconds, growing out a wall of roots 1200/1300/1400 units wide a static distance in the target direction, preventing all enemy movement including blinks, dashes, jumps, etc. from going past the roots. Casting Ancient Tree does not disrupt Meditation.

While the Ancient Tree is summoned, Master Yi heals allies around the tree while he is Meditating and heals himself for 20/30/40% more.

UPDATE NOTES:

Wuju Style: Cost lowered to 45 - 65 from 50 - 90 mana Second strike base damage lowered to 30 - 50% from 40 - 80% Passive added that reduces the BASE cooldown based on bonus attack speed from items, up to 4 seconds reduction, CDR reduction applies after this reduction.

(This makes it where attack speed Master Yi is around, but not reward that mindless, binary gameplay. So you can still do AD/AS Yi, but still have it have some kind of gameplay to it and not be "press R and AFK" like how Yi is currently. I want actual thought process and gameplay to Yi which helps tone back his dominance in low elo naturally with some kind of thought process implemented to his gameplay.)
