I'm honestly sick to death of tank assassins

Almost every game I'm getting assassins that are building either full tank or semi tank, becoming near unkillable, yet still functioning as an assassin.

tank akali and master yi are just the tip of the cancerous iceberg. Yasuo, zed, fizz, and ekko....multiple games now with these fuckers opting into a tanky route yet still maintaining their ability to delete targets. It's asinine. They already have ungodly amounts of mobility to help maintain their safety, yet they are now gaining the ability to facetank to remove their intended weakness.

It's quite silly how frustrating it is to play against them, regardless of role. It's bad enough to be deleted by an assassin without much counterplay options (when Zed is the posterboy for a healthy assassin kit you know there's issues). But, these tankstrocities turn that BS all the way to 11 when they jump on your face, beat you too death while facetanking all damage, and than run away because their escapes/initiation spells are back up. Atleast assassins built in the traditional sense usually die when getting caught out in a bad spot, but tank assassins just shrug all the damage off while blowing your carries away to kingdom come.

The high risk/high reward playstyle that assassins are supposed to have is instead changed into a very low risk/medium to high reward. Why wait for the perfect time to strike a squishy target? Can just jump in there, soak up the damage, and smack the carry till he's dead.

TL;DR get rid of the ability for assassins to opt into a tanky build to become durable whilst still maintaining their ability to assassinate well. It removes an intended class specific weakness neccessary for balance purposes.
