Master Yi needs to be included in the assassin update as a big project.

Master Yi has everything needed to be included in this update. He shares many traits with the updated champions before they were changed NOTE: i can already see this being an issue so let's make sure this is clear. In my comparisons down below I'm referring to the champion in their pre updated state.

Sees no pro play like almost every champion to that has been updated or confirmed to get an update.

Unless he's overpowered there is no reason to pick him like Vel'Koz.

Has unhealthy gameplay patterns like Morde.

Lack of meaningful/clear counterplay like Malzahar

Fails to stand out in his class like Zyra Miss Fortune Quinn and Corki. That is unless of course he's overpowered then he shines for all the wrong reasons like Cass and Vladimir.

Thematic could be done better like Graves.

Unless he's overpowered, Master Yi doesn't feel rewarding to play just like Darius Skarner and Garen.

And finally, Master Yi's kit has abilities that just feel flat out useless in most conditions like Caitlyn.

I don't see a reason why master yi would be passed on for the assassin update. He's got everything needed and more for a slot among the big updates.
