If we were to make improvements

The Destiny Guide Gacha is essentially a dud unless you get characters or diamonds, so it should only drop characters. Allow players to aim for multiple limited characters and increase the probability. Bundle the equipment gacha together and reduce the performance difference between each equipment. Reduce the number of enhancement materials (too much water and adamantite). Set the maximum level to 100, rarity to 4 tiers (SR, SSR, UR, LR), and make performance increases minimal. Reduce the quotas (amount or number of opportunities for daily, weekly, etc.). Review the contents of shops and paid packs (especially remove overpriced items from the shop). Implement elements other than limit breaks and equipment to strengthen characters, allowing for differentiation. There are probably many other things, but I think it's bad that it takes too much time and materials for character development. Perhaps because of that, the gacha and materials are unnecessarily numerous and cluttered. I think the development system should be reviewed so that players can try out characters and team compositions to some extent. If there were major revisions, compensation for players (especially paying players) would be necessary... but I think that can be worked out somehow. I won't consider the super whales who have spent hundreds of millions of won.
