For example, normal "Pity" is 50 spins for basically 1 lucky spin as seen on the photo attached, which is mediocre no hate, i think in my 5 months of playing gacha games by chrollo I've gotten a mythic from a pity just once, anyways this mythic pity system would be like the photo attached, but instead 100/100, and it would be like other gacha games, for example, Honkai: Star Rail, you can roll around 80 times for a good character, and if you dont get it, on your around 70-80th pull, you're guaranteed a 5 star, but you can also choose a 5 star you want, and its a 50% chance to either be the one you wanted, or a random 5 star, now think about that but in BBZ, For example, Mythic Pity 0/100, you can click on the mythic pity to choose a mythic you want, now once you hit 100/100 pity, you have a 100% chance of getting a mythic, but only a 50% chance that its the one you chose in the pity menu. this pity system is also seen in other games, like Volleyball Legends, but for secret styles.
I think this would be a good addition as atm the game feels bland with spinning, and you don't really get any compensation for spinning hundreds of times and not getting the thing you wanted, which i get makes sense because you are playing a gacha game after all, but almost 100% of other gacha games have a pity system that guarantees a mythic/5 star/secret after a certain amount of spins.
This would also encourage farming the AFK chamber, and buying spins.
If the devs do read this and you think it's unbalanced, maybe it can only be charged up with lucky spins, but i also think thats a bad idea considering how much 100 lucky spins is, if you were to make it charged up by lucky spins, perhaps lower it to 50/50 like the normal pity.
