My Vote: Devotion/ Vengeance Paladin or Hexblade Warlock.
I'm sure that someone will get a Hexblade into the game if Larian doesn't, but that doesn't stop me from wanting to play one. But if we're stuck with just the PHB, then getting Paladin to test out would be nice. Though making Smite work will be interesting, since it's a decision made *after* you hit.
