I really hope they can fix TFT

It just feels so unbalanced, With the item RNG it is possible to get 1 item with the first wave of minions while others can get 3 or more. Then there is the Champions. Whenever i am looking for a certain champion I can never find them, BUT when I sell them to build another champion up THEY ALL SUDDENLY APPEAR. I can be in the final 3 and have no 3 stars but others can have one on round 2? Even later in the game when you need another garen? Sorry but you're level 5 you can no longer find commons anymore.
