What do you think about the latest update?

I watched a YouTube video about the latest update.
It looks like we’re getting a new Arch Boss and a bunch of other changes.
I also heard that the Delulu weapon is getting buffed. Do you think it’ll become a level 80 weapon?
What do you all think?
I’m currently building my gear and was planning to go with the Heroic Staff, but if Delulu is becoming level 80, maybe I should wait and build that instead?
