With the talks of other gacha games, I used to religiously play King's Raid but stopped once they started greedy and added in more randomness in the gacha. Before this the game was very fair with characters being obtainable by ingame currency, but during a summer update they added in accessory slots to every character, along with unique accessories. This was just cruel as actually getting them was 3%, and to add salt to the wound the new story update made prerty much all of the old dragon equipment obsolete. This only left you to either waste a good chunk of money rolling for unique equipment or hope to god a group of whales would let you join in the raids, but still waste a good chunk of time farming dragons. I just stopped as the grinding got too much, with barely anything to show for it.
