Curious why can't I create a GA for Quake Champions?

cause game in humble monthly isn't full?

I'm guessing someone on staff decided that it made more sense to remove a preorder category (ie, exclusive benefits) game which'd automatically update itself to 0CV in the future, once the game left Early Access [notably, in the same way any game that eventually goes F2P does, with such games being ones that staff doesn't pre-set value on], than to give temporary CV to people who actually paid an amount of money that matched to the CV given.

My guess, they confused paid Early Access with free Beta, despite the EA perks of the purchase, ignored rational valuation considerations, and just went "NO, BETA BAD." and then spent the past few days slapping angrily at beta fish, to distract themselves from having to decide if they should pretend to at all care about bigotry-derived forum toxicity.

(Alternative hypothesis: Quake Champions went free beta on Steam through the remainder of EA somewhere (though I can't find mention of it), and staff made a drinking game based on inappropriate forum comments, and they only just got out of intensive care.)

If you have the Champions Pack that Steam is selling, you should be able to request for support to add it.
Quake Champions it self is as noted above is free game that is not release just yet.
