i have other 2 accounts, which have 1 coupon each, all coupons are from the the first day of this ' new ' event, i think they change the coupon probability afther the first day. I even got a coupon from the very first dice. although I didn't get a coupon in this account, after 129 dices. I got a coupon for redeeming japanese 120 EBB, and that's enough for me, because all other ebb/ecv seems doesn't better than the bb6/cv6.
..... i forget how to speak english.....
