A 3rd party app like TFTactics.gg for Overwolf shouldn't be necessary.
All this app does for me is show me what items combine into, and what the probability is for each price point champion to drop in the current game state.
These are fundamental pieces of information to playing this game.
Why are they hidden from me -- so much so that I have to go download a 3rd party app to see them in-game? Or navigate to a website in a browser in another window?
Why is there no tab menu with this information?
I shouldn't need a 3rd party application for this.
Also, TFTactics.gg has an absolutely wonderful addon for overwolf that's just about the best thing going out there for TFT -- I suggest it for everyone. Its lightweight, easy to use, and gives you everything you could possibly ask for IN-GAME. No more alt-tabbing to check another window.
At least until Riot fixes their shit.
