I think I see where the OP was coming from.

Where say in 2.0, all gladiators are just paladins from the start. And setting a Paladin Stone ability on your action bar locks out cross class abilities. Still the armory system, with job names instead of class + job names.

I wonder if we'll reach a point where we just change classes via stones/drop downmenu, then wield more types of weapons on a class. Favor, required, and exclusive traits still influencing how we lean.
