I don't know if NA will become like CN in regards to the ability to obtain Hokage Minato. On CN its currently only available to the highest spender. I'm sure you've noticed that the hokages are slowly being phased out of events aside from Tsunade. If they aren't phased out, you either have to drop mad amounts of money to get one or get lucky in 1 ingot sales. Also I honestly don't have an issue if someone gets him off a free spin. Its just luck, and this is coming from someone who bought him a few event cycles ago. Only a handful of people had him so its good to see him getting more gameplay. Plus paying for a ninja just gets you them ahead of time. Never has been an exclusive thing. I pay but have gotten lucky in regards to drops (Tsunade 5th hokage, Hashi, and Tendo). It happens and gives people an opportunity to get something if they cant pay. I personally like the tendo drops this cycle though. More people can obtain him. I'm usually against Oasis but they did well this go around with assisting with ninjas and frags.
