In my opinion, No.
You may as well get mroe powerful skills with ceratin buffs than have 2 weapons.
Not only does this take AGES to master to use properly, but its tedious.
More cost for 2 weapons, Repair worries, less quick slots.....
You can always have a good shield at the ready for a speedy exit but you dont need a new mastery set for that =)
Cheers
