Yes but if you make SK dual wield they have to be able to wear a shield too. That's quite a class defining feature.
I reject your logic based on the fact that SK and PAL are completely capable of wielding a two hander and in this game, that is the class defining feature as the heals are better with that for Pally.
Also, one can wear a shield such as SOA on back.
Dual wielding is cool though...
