i want to see the drop rates for items

That's how randomness works. Since it's random, it is completely possible for you to get the same item 6 times in a row, though I will admit that the chances of that happening are low.

Wow, unkillable 2 stars Mundo with 2500 HP and 400 hp/sec heal. Not to mention his ultimate.

Unranked Toolmaker, start to play ranked games and then talk about TFT.

You never build anti item to combat a specific unit belonged to a specific opponent.

Players always build items according to their ADC/APC /Tank units, unless their units have 3 items very late game and they still need luck to grab that anti-item from carusel.

I saw many times a very good win streak, top 1, using one Warmog on 2 star level 1 unit.

In TFT this "build something to combat something" is just a dream to fall asleep children.

Look at "Disguised Toast" and "Scarra" video-stream they never complain about items and they still win.
