Yes they did, but not because of ninjas, because no content. They went on and on how we must rush to catch up to china version so we can just get their updates and then we passed it and never had new content since then.

Think about when was last time we actually had new conent? Half of tsunade npc that they lied and said she is added fully, when she isn't. China already had more plot, lvl 110 cap, more group levels, more team slots and few more new systems for maybe a year now not sure. We just geting recycled events and only new ninjas + outfits.

I think ever since we got refines and rune stones upgrade that china declined, our version is incompatible so we can't just copy their patches. At least that's what it's starting to feel like, we are in maintenance mode till game closes for good. They really need to do something like 7.0 and new stuff because many players who played for years are quiting.
