Moriyama you have wrong understanding about Skirmishers and you should read in the Skirmishers page about it

Skirmishers are light fragile fighters that are armed with situational defensive tools to survive the fray and are aimed to shred any nearby enemy units, including tanks, and they lack the high end burst and mobility of assassins Such champions are Master Yi(flat true damage and excels with onhit effects), Fiora (max health true damage), Yasuo (Bonus armor pen) but I also consider Vayne (max health damage), Vi (armor reduction and max health damage) and so on.

Assassins on other hand are able to easily close the gap to the important targets such as Marksmen or Mages and quickly execute them since they have high burst damage and higher mobility which is greater than Skirmishers' So while Zed and Talon executes the back line, Master Yi and Fiora fighters the front line and when the important target is close enough they can engage on them

Nearly every champion in the game have some sort of CC – Fiora can parry hard CC and have slows on her E. Yasuo has knock up, Riven has high damage, mobility and CC, Jax have stun ward jumps and so on. Currenlty Ekko's Z-drive resonance makes him much faster than Yi's Highlander and Ghost. During Yi's Hghlander Fiora was chasing me with Trinity force, ninja tabis and spamming Lunge. Katarina has no CC but she is far more mobile than Yi

That said adding at least one ability that slows enemies to Yi's Kit and extra mobility makes sense since he is under Mobility Creep and he is the only champion that have no CC

I would also like to point out that I removed the free damage on Wuju Style

Passive - Wuju Style: Grands 30% AD bonus true damage to Alpha Strike and each hit from Master Yi's basic attacks against enemies marked by Wuju Dagger
