Anything that you have seen close to dual wielding in M&B was just replacing the shield model with a weapon model but still only works as a shield
This I would be fine with, as Florentin style was not that rare, and would spice up the battlefield while not impacting gameplay in a negative fashion.
However, I do not see the developers bothering to do this, and would rather them implement the strategus fix so it actually comes out sometime this or next year, as opposed to 2014.
