How to improve the shop and make it less based on "luck"

How to win :

Pick Lucian, feed him 3 adc item : and GG... Protect him with somes champions from assassins but if you can get this build, you win. Also max him 3 stars.

I feel like the only viable strategy is to put all items on an adc like Lucian or Vayne to win TFT. Items are going to be a problem to balance.

Also other thing that bother me :

I pick Garen, i buy some garens (trying to get him at 3 stars) and the shop make everything to prevent me from maxing my garen.

I get Nidalee, Lissandra, Sejuani, Kennen but i don"t want these champs, i want Garen, Fiora, Ahri. I like them, i want to have them, yet the shop don't want you to buy your favorites champs.

I reroll, like 10 times and not a single Garen, not a single Mordekaiser. Spend like 10po without a thing that can interest me.

How players can get their champs at 3 stars ? It's pure luck. But 3 stars champs are so OP and powerful. 1 star is useless, 2 is good but 3 is godlike, especially adc.

One champ on the shop should be one of the champs you have placed on the map. Otherwise it's so much random and unfair. Some people can have 3 champions with 3 stars by luck and others players can't even max one champ to 3 stars.

Also, i sell Varus because i see no pairs. The next round, what i get in the shop ? 2 Varus that could have been combined... I feel like this is a pure joke. Champs that we sell shouldnt appear on the next round in the shop, because if we sell them, it's because we don't want them. So what the point of putting Varus in the shop when i sold him ? And when i reroll 5 times and there's Nidalee, i don"t want nidalee, why you show me her more and more ?

Pls, make the shop a little less random. If you want TFT to be fun, then we should be able to play and max our favorites champ, not be forced to pick Nida because the shop don't give us pair, even with 10 rerolls.

It's would make things better.

Why not make shop like this ?

1 place for a 1 po champ ( for example) 1 place for a 2 po champ ( ) 1 place for a 3 po champ ( ) 1 place for a 4 po champ ( ) 1 place for a 5 po champ ( ) 1 place for a random champ that you placed on the map. For example, if you placed Fiora, Lulu, Garen, it's will give you between the 3). 1 place for a champ that you don't have, neither on the map or on your stock. It's can be 1po, 2po, 3 po...

By this way, it's will be less fustrating, reroll will have more sense and the shop will not be based only on luck.

For the 4po and 5 po champ, we can replace them on the shop by 1 or 2 po champ and add them when the player will have a better level.

For example players beetwen lvl 1-4 will have on their champ :

2 places for a 1 po champ. 2 places for a 2 po champ. 1 place for a 3 po champ 1 place for a random champ that you placed on the map. 1 place for a champ that you don't have.

And players above lvl 5 will have :

1 place for a 1 po champ 1 place for a 2 po champ 1 place for a 3 po champ 1 place for a 4 po champ 1 place for a 5 po champ 1 place for a random champ that you placed on the map 1 place for a champ that you don't have.

Because having Leona in the shop at level 2 won't be very useful so...

What do you think of this idea ?
