You aren't the only one, it's been full year since 6.0 where we got nature trainin last new feature and few other small things. This game feels abandoned at this point, especially if you play china version too and see their version still gets new feature or rework every 2 months. We just get ninjas and outfits that they can sell easy.

Am still annoyed we got scammed on tsunade npc that doesn't even work properly, and their bullcrap excuse even though they accidently added her working as intented before but removed, people even have her instance materials in their inventory still.
