Im curious why your conception of a warlock must be able to be confused with a wizard or sorcerer from an outside perspective. That has never been an aspect of warlocks in 5e that I valued, or something I particularly wanted to emphasize.

To me, a warlock character could be made using any number of classes present in pf2, including the aforementioned sorcerer, wizard and witch, but also the psychic or oracle. The fantasy of having a patron is not something that must be expressed mechanically IMO, because it ultimately boils down to “you have a connection with this powerful NPC and you need to consider their wants/needs/demands or else there may be consequenses”

Skyblivion is set to release 2025 if i remember correctly.
