yeah, but beeing limited to two weapon sets is a bit too dull ...
I like the idea of skills bound to weapons/armor and I think it would be quite nifty if you can change between every weapon you carry during a fight, maybe with a short/medium cooldown (make the decision matter) ..
tied to a elder-scrolls like weight limit we might see warrior-archetypes carrying an arsenal of different weapons with different skills, whereas rogue-archetypes carry less weapons but they are able to switch the "handling" of the weapon (different fighting styles, different skill set while sneaking, ... ) and the mage-archetypes have access to a lot more spells/spell schools
