lucky board is good event, but if you are f2p you must save coupons to get ninja in this event, so if you saved 20k it will take like 4 months, and this event come one time every month right ? that mean for f2p they see this event 4 times until they have the coupons to buy a ninja, in this 4 times you can only use 2 dices per a day, and that is too low, you can get 14 dice in this event for free, and every dice give 5 points, rarely 10 points, so you will get only 70 points in this event if you got 5 points on every dice and 70 points can give you only one frag of hiruzen or danzo, it will be so much better if you can get at least 5 dices per a day, in genera mobilizaion event you can get 10 frags of rare ninja for free in the event, and in lucky board you can get only 1 frag for free
