Terminalvertex hit the nail on the head. Mobage's lack of foresight in designing the basic structure of this game has doomed it. Cards & weapons that only have two meaningful statistics (ATK & HP), and absolutely no distinctive card or weapon skills, means there was only ever one path open to Mobage to keep the whales interested: keep turning those numbers up, and up, and up, and up.

It was inevitable that the growth curve would go exponential, and at that point every other structure in the game breaks down.

Kind of like the "take a penny a day, double it every day" parable. It seems easy to do at the start, but by the end of the month...
