TFT is just a slot machine for underage kids.

Its a deck builder game. Which gives you agency to impact RNG.

Do you know what the drop rates for a 1coin unit are at level 5? How many champions are in the pool?

Replace "TFT" with "Hextech Crafting" and you're 1000% spot on.

So you are telling me that gwtting a team of:

Yasuo Karthus Mf Anivia Kayle Swain Pantheon

I instantly win?

You must be the type of guy that chooses champions over items in the Carousel.
