I personally find this game to have somewhat fair gacha rates, better than most of the other f2p gacha games. great story. great characters. really pretty artwork. incredible soundtrack. each major update brings new visible improvements.
While this is vastly better than the global offerings; the gacha will drain you everytime. There is even a gacha for paid offerings... which seems like a more exclusive way to drain your money. I would be less skeptical if I wasn't taken advantage of by Fuji Gumi's other offerings; and outright raped by Gumi's global gacha offerings on all of their platforms. Other than my critical opinion of their gacha system, there is suprisingly alot to do. Even when old event cycle around; it makes the nostalgic player want to catch the missing Alchemist shard/soul before the event runs out. Some events, though for beginners, offer some good gear or souls. Not the best tier souls, but decent nonetheless. And each soul has an intresting story or relational tie in. All in all I like the game; but I will not play it for long stretches because of the gacha. On the global version, I try not to play it at all.
