Yeah, this is my impression. It's had slightly better rankings, and the editorial staff probably has more faith in Shiibashi and what he might be able to create. He's kind of been in the WSJ circle even longer than that, having been an assistant to Araki.Not safe, just safer. WSJ is trying to preserve it, similar to what they did with Kurobas until it became popular. Can't say I am surprised seeing that NuraMago also got special treatement.
So, favoritism? I can't really speak to that, as I haven't read the new series from the last rotation. It would only be to my tastes anyways. But this kind of thing happens often.
