Most of you who played the culling know that these devs did a big mistake on the rarity of items. They had for example hundreds of items with pretty much the same rarity, and the most rarest item could still be easily getted by winning the tournament with coins.
The drop rate of items should have each level, for example.
for the rarest chest by winning the game, you should have like 1 in 100 chance or higher to get the rarest chest by placing number 1 in ranks.
Items should be very hard obtainable, this is what makes the game fun and other players want to show off ofcourse. The culling did a mistake and pretty much everyone could have rare items and it was easy to get.
