If we're sticking to just 2 subclasses (which I hope we're not), I have a feeling Ancients and Devotion are the ones making it in.
Oath of Vengeance is probably my favorite Oath in PnP (mostly due to its spells), but I can see with the way advantage has been implemented in the game (backstab = advantage), vow of enmity becomes redundant so Larian would focus on those two.
