i buy the monthly coupon card. 50 coupons a day for 30days. i dont consider myself p2w. but some said i was cause i had roshi. now because i have edo kushi,sasori,exploding sword guy (always forget his name) but fact is i been playing for 2 years and the only (lucky) ninja i ever gotten were swimsuit ino, and Nara (which is in the shop now) and i certainly dont see a point in spending any more then that considering that awful luck i have.
