I'm hoping that the "traditional" classes are more like class mods. For instance, my Gladiator at level 40, I could change between the existing Glad mods to become a PLD, or Soldier, or DRK any time that I could change my weapon. Each one would have a few automatic traits such as Defense bonus, critical hit chance bonus, or attack bonus, and would give access to a few abilities/spells/ws's exclusive to that mod.

I hope they also make changes to existing abilities, make more of the abilities exclusive to their native class, maybe move a few around, and make WS's exclusive to their given weapon.

As an extreme, I'd also go back to a standard class change system where you change your class by picking it from a list, just allow people to change at the same times that they can change now. Limiting each weapon to a single class, is just that, limiting.
