You're confusing individuality, which is exactly what the armory system allows, with pre-defined roles, which it definitely does not do. There's a huge difference.
If you want individuality, then you want the armory system. If you want to be pigeon-holed into a specific gameplay setup, then you want the traditional definition of an MMO class system.
If you want a mix of your own type of gameplay, but want to transmit to people that such and such role is what you do, then you should be all about option 2, which calls for class augments and specializations.
