Leauge issues since TFT, Lets delete it!
Seriously though its so buggy, unbalanced and this bad game mode is causing issues on the whole client. I love tactical turn based games but this was released a bit premature. This honestly should have been given its own client. Too much spaghetti code and deleting TT on top of it? Im sure Riot would have done it sooner if they could figure out how to not make the whole client crash in doing so since the last time they did anything real with TT was 5.11.
Give TFT its own client or mobile version and get it out of the League client. And chill with skins. Id rather have a functional game. 
Also TFT just plain sucks anyway.
