Imballance Tournaments Rule

I think the developer have to fix about the rules at the tournament.
They have to separate class tournament into some classifications based on the player’s dino rarity used at the tournament such as:

1.Common (all common dino are allowed in this tournament)

2.Rare (all rare n common dino are allowed in this tournament)

3.Epic (all epic, rare n common dino are allowed in this tournament)

4.Legendary (all legendary, epic, rare n common are allowed in this tournament

5.Unique (all rarity are allowed in this tournament)

the rewards also different from every class,
so all player can pick which one the suitable tournament for themselves also they will meet opponent with equal capabilities

thank you
