10 tails madara would never be avail in coupons on servers that Oasis controls until China does so. If the original starting server have not done so, why would any other server have incentive to do so? Oasis has yet to implement changes that would be better for the player base overall in comparison to Tencent has with the China server. They only made changes when whales don't want something (% tactics, and refinement update). Of course I do not know if these changes to survival trial happened in China as I got locked out from my account last year.

Also this frightened behavior from people here on the forums happened when for the 3v3 boxes were released. Some of you were quick to assume they nerfed when you haven't started seeing edo jin shards for a few days. Y'all just gotta wait, record your rewards, and figure out the drop rates before you jump to conclusions. You also can't really assume the drop rates by just one day or even one week, but one month should be fine as that is after all one event cycle. Just because the edo jin shards have a lower rate doesn't mean it has been nerfed.
