I don't mind that the update is coming out in phases but I agree that communication was lacking. It was a letdown not to get cross server arena and i'm not sure what aspects of the home screen we are getting or if GNW packs or format have been updated or not.
It would have been a really simple thing to let us know that the features would be coming out in phases instead of a complete overhaul and saved everyone a lot of confusion.More clear communication about what features to expect, perhaps when the next update will be, and what features have been implemented would be even now very beneficial.

As far as the combo simulator, I disagree. If given the choice of phased updates or waiting until the combo simulator is finished, I would have picked phased updates. Sorry you feel otherwise, but for me, having GNW white list, new TIs, Kakashi Handbook, sealed ninjas are more important than the combo simulator. Just my opinion.
