I can't really speak for another server, however i can tell you that rates here are anything but low. We've had 4 deidaras so far, all for people with 20-30 spins. Considering how expensive of a ninja he is, that's what i don't consider entirely fair. Not getting him after spending 2k coupons? Sorry, i know for a f2p that's quite a big amount, but you knew this outcome was possible on an rng event. Deidara is by no means supposed to be worth that little. There are people with over 500 spins, even 1.5k that don't have him. I've spent myself over 3k in lucky stars. Did i get Masked Man? No, but that was the most likely outcome. At least it had items i could redeem for that price, just like this wheel isn't entirely bad either.
