8/9 months for server 1 and 2 i think it was

they also take the number of active players on each server into consideration,
so it is possible to have server 5x merged before 4x

generally speaking, the ones at 50 and 70 are better, but you can still draw a few times now to get better ninjas for your team

lv 70 draw seems to be pretty small compared to 50draw and seal treasure. Will they announce new ninjas soon?

They do change around the available ninjas in the treasures once in a while

I hope it's 8 to 9 months from now, but they're releasing servers so fast it's ridiculous.

"So a new server is the best way for a new player to start out. Each server ends up being a tiny community of people and each one has people cash shopping their way to power to be number one. If it was just a single giant server there would be no incentive to spend money because some rich guy will outspend you every time."
