Well they are getting both getting auto attack I believe but only at close range like in FFXI. They also said Archers close range auto attack would not use arrows, this could be a hint at them being able to equip another weapon like a knife.

Also the suggestion that mages also have to be close range for auto attack make me think that they will actually hit the Mob and not use Spirit/Phantom Dart, if this is the case are they gearing up for a bigger change to the Class system than we know, hopefully the removal of Weapon=Class is on the cards.
