Some suggestions for TFT

Hello all. I believe many TFT players would agree, that RNG very frequently overweighs any skill, especially in the second set of the game. I was thinking about it and came to some ideas to make more balanced combination of luck and "calculated" deckbuilding. I don't know whether community will agree with me, I just like to share my ideas with other TFT players.

1. It's necessary to show the number of any champion copies still available in the shop. Now you can reroll 10 times to find 1 lacking champ and get nothing because all the copies were already bought. It's very annoying. This information can be easily added to the right-click menu, and it will help players to plan their expenses.
2. I suggest the option of buying ANY champ you already have at ANY moment of the planning phase for increased amount of money. For example, Tier of the champion x4 + 1 gold for each use of this option. (so, Nasus or Zyra would cost 4 gold for the first time, Lux would cost 28 gold) It will remove the gold waste for unlucky rerolls, but luck will be still important, cause it will help to save money.
3. Winning a PvP round should give 1 exp instead of 1 gold. The same logic - gold can be easily wasted, exp is always valuable.
4. I would suggest also to tweak item drop in PvE rounds. Chests with random champions help very seldom, so it's better for them to be removed from the game. I think it would be good to increase the chance of dropping gold and decrease the chance of dropping items, but also to make an opportunity to buy a certain number of basic items (except spatulas) for gold after each PvE round as well. In addition, I want to note that PvE rounds in TFT are too easy. Perhaps it would be good to make them more challenging. To sum it up, today the gold management in TFT barely depends on the amount of your luck. I love the initial idea of TFT and want to see it moving to more deep and well-thought deckbuilding:) It will be interesting to hear other players' opinion of this
