I don't know if this has already been talked about but I feel the need to just put it out there, as it has been stressing me whenever I level any of my accounts as they are all evil. I used to just level in Oto and make my rounds simply without having to worry about the ANBU, yet now with the new changes Iwa was supposed to replace Oto with the forest and academy, yet the Evil ANBU or Black Dragon ANBU is completely gone in every village. I didn't mind it the first couple times, yet when I have a Hyuga account with 0 weap at level one its near impossible to beat the ANBU in which they now come more frequent then other events.
I apologize if you are already looking into this, yet I wish it can get done faster if not then actually put into place.
As for a suggestion I wouldn't mind the Evil ANBU being located within Iwa or Kumo, whichever best fits.
