I suggest a change in the ninjas of the last level of the tree. Nobody wants Hashirama and Jiraiya, Jiraiya is still a meta but almost everyone has it and he still comes in the fuku package. It's only worth spending on the tree if it's more than 100k and with these ninjas there's nothing. On the Brazilian server they have a package of Jinchuriki and Otsusuki. At least add those packs with indra, ashura, Obito Jinchuriki and Madara Jinchuriki. Or maybe a Pain and Gaara. Pain hardly ever comes to events.
