Cup level explanation?

[Moi]

Cup groups don't have levels, like League groups. You can be level 14 and play on a Cup with other non 14-level teams, although we try to create groups using teams with similar quality levels.

We all know that players manipulate cups, but that isn't the main problem, the main problem is when there is a difference of 3 levels between managers and these managers go to transfers to rebuild/reinforce the team. For example, the manager in level 17 can buy players with 3 more stars than the manager in level 14, because the market has a limit of 5* players.
In the level 17 the "garbage" players from the market are 5* in the level 14 market. The 5* or 4* or 3* players from the level 17 market cant be bought by the level 14.
There is a huge gape of power.
