if companies were to be added then SE would have stated that.
Companies will be NOT added, however next weak SE will release info on companies.
I would also not expect AA or any other features.

A more detailed report can be found in the 1.17 patch notes, scheduled for release on April 14

"A more detailed report" does not mean that key-features were left out in this post. It berely means that there will be more notes explaining the content of this update.

I wonder what NM will be added, new models or if some existing mobs will be reused.
Also happy to hear about new gear.

Thanks for the update SE!

cheers
