Like I said the only people that gem them are the ones who have a lot of money, are impatient, or just lazy. Otherwise, no, I believe 99% people don't spend a dime on LTQ. Call me crazy, but I think it's a ploy by Gree to make players feel like they are cheating the company to get free crap and making their "player stronger." Thus having the effect of them actually getting addicted to the game and spending in the future.
