I don't think the rates are that shoddy. Sure maybe 1 or two people may get those 80 frags but that's how it should be. Check out the forums and see how many people received Hokage minato these past weeks. Plus if you are spending with the intent of getting him from there, that's your own fault honestly lol. Similar to buying dice for the lucky ninja packs for a CHANCE at hashi or tobi rather than spending toward the redeemables and getting ninjas from packs as a bonus. Spending towards luck based is never wise but that never seems to stop people. Also I believe a mod stated the sign in's are primarily geared towards new players as incentive to * with the game and give them decent characters to start. Plus, they'll never give away a caliber ninja so if that's what you're hoping for let that dream die right now lol.
