Well for starters we need to quit pretending its pre-alpha. The game is less than a year from launch. It should have already (or more likely already has) started beta.
What you see now is going to be very close to the final product. (especially since we have been getting updates for 6 months and nothing of note has changed in any of the reveals)
What you are saying here seems like complete assuming based on 0 sources? Apparently there is a rule now saying "software that is 1 year away from launch must be in beta state"
Who said we are less than a year away from launch btw? The game is *planned* to go live in "late 2022", there is no official release date and the launch could easily be postponed to 2023.
And nothing has really changed since the SP test in July? Are you sure we were playing the same build?
